Add complex erf,erfc,erfcx,erfi,dawson routines from Faddeeva package.
* libinterp/corefcn/mappers.cc: Add erfi and dawson mapper functions,
and add complex-argument test cases for erf, erfc, erfcx, erfi, and
dawson.
* libinterp/octave-value/ov-base.cc, libinterp/octave-value/ov-base.h:
Add erfi and dawson mapper functions.
* libinterp/octave-value/ov-complex.cc, libinterp/octave-value/ov-cx-mat.cc,
libinterp/octave-value/ov-cx-sparse.cc, libinterp/octave-value/ov-float.cc,
libinterp/octave-value/ov-flt-complex.cc,

libinterp/octave-value/ov-re-mat.c,
libinterp/octave-value/ov-re-sparse.cc,
libinterp/octave-value/ov-scalar.cc,
libinterp/octave-value/ov.h:
Support erf, erfc, erfcx, erfi, and dawson mapper functions for
real and complex matrices and scalars.
* liboctave/cruft/Faddeeva/Faddeeva.cc, liboctave/cruft/Faddeeva/Faddeeva.hh:
liboctave/cruft/Faddeeva/module.mk, liboctave/cruft/Makefile.am:
Add Faddeeva package (from http://ab-initio.mit.edu/Faddeeva) to
libcruft, to provide the various complex-argument error functions.
* liboctave/numeric/lo-specfun.cc, liboctave/numeric/lo-specfun.h:
Add complex-argument erf, erfc, erfcx, erfi, and dawson functions
to liboctave API. Delete previous real-argument erfcx implementation
in favor of Faddeeva::erfcx (which seems to be slightly faster
in gcc/x86-64 benchmarks, with similar accuracy).
* doc/interpreter/arith.txi: Include erfi and dawson documentation.

456 |
| 10118 | 457 ** The `lookup' function was extended to be more useful for |
| 458 general-purpose binary searching. Using this improvement, the | |
| 459 ismember function was rewritten for significantly better | |
| 460 performance. | |
| 9352 | 461 |
| 462 ** Real, integer and logical matrices, when used in indexing, will now | |
| 463 cache the internal index_vector value (zero-based indices) when | |
| 464 successfully used as indices, eliminating the conversion penalty for | |
| 10118 | 465 subsequent indexing by the same matrix. In particular, this means it |
| 466 is no longer needed to avoid repeated indexing by logical arrays | |
| 467 using find for performance reasons. | |
| 9888 | 468 |
| 10118 | 469 ** Logical matrices are now treated more efficiently when used as |
| 470 indices. Octave will keep the index as a logical mask unless the | |
| 471 ratio of true elements is small enough, using a specialized | |
| 472 code. Previously, all logical matrices were always first converted | |
| 473 to index vectors. This results in savings in both memory and | |
| 474 computing time. | |
| 9480 | 475 |
| 10118 | 476 ** The `sub2ind' and `ind2sub' functions were reimplemented as compiled |
| 477 functions for better performance. These functions are now faster, | |
| 478 can deliver more economized results for ranges, and can reuse the | |
| 479 index cache mechanism described in previous paragraph. | |
| 480 | |
| 481 ** The built-in function equivalents to associative operators (`plus', | |
| 482 `times', `mtimes', `and', and `or') have been extended to accept | |
| 483 multiple arguments. This is especially useful for summing | |
| 484 (multiplying, etc.) lists of objects (of possibly distinct types): | |
| 9408 | 485 |
| 9449 | 486 matrix_sum = plus (matrix_list{:}); |
| 487 | |
| 10118 | 488 ** An FTP object type based on libcurl has been implemented. These |
| 489 objects allow ftp connections, downloads and uploads to be | |
| 490 managed. For example, | |
| 9880 | 491 |
| 10118 | 492 fp = ftp ("ftp.octave.org); |
| 493 cd (fp, "gnu/octave"); | |
| 494 mget (fp, "octave-3.2.3.tar.bz2"); | |
| 495 close (fp); | |
| 9880 | 496 |
| 10118 | 497 ** The default behavior of `assert (observed, expected)' has been |
| 498 relaxed to employ less strict checking that does not require the | |
| 499 internals of the values to match. This avoids previously valid | |
| 500 tests from breaking due to new internal classes introduced in future | |
| 501 Octave versions. | |
| 9449 | 502 |
| 503 For instance, all of these assertions were true in Octave 3.0.x | |
| 504 but false in 3.2.x due to new optimizations and improvements: | |
| 505 | |
| 506 assert (2*linspace (1, 5, 5), 2*(1:5)) | |
| 507 assert (zeros (0, 0), []) | |
| 508 assert (2*ones (1, 5), (2) (ones (1,5))) | |
| 9462 | 509 |
| 10118 | 510 ** The behavior of library functions `ismatrix', `issquare', and |
| 511 `issymmetric' has been changed for better consistency. | |
| 9873 | 512 |
| 10292 | 513 * The `ismatrix' function now returns true for all numeric, |

514 logical and character 2-D or N-D matrices. Previously, `ismatrix' |
| 10292 | 515 returned false if the first or second dimension was zero. |
| 516 Hence, `ismatrix ([])' was false, | |
| 517 while `ismatrix (zeros (1,2,0))' was true. | |
| 9873 | 518 |
| 10118 | 519 * The `issquare' function now returns a logical scalar, and is |
| 520 equivalent to the expression | |
| 521 | |
| 522 ismatrix (x) && ndims (x) == 2 && rows (x) == columns (x) | |
| 523 | |
| 524 The dimension is no longer returned. As a result, `issquare ([])' | |
| 525 now yields true. | |
| 9873 | 526 |
| 10118 | 527 * The `issymmetric' function now checks for symmetry instead of |

528 Hermitianness. For the latter, ishermitian was created. Also, |
| 10118 | 529 logical scalar is returned rather than the dimension, so |
| 530 `issymmetric ([])' is now true. | |
| 9873 | 531 |
| 10118 | 532 ** Function handles are now aware of overloaded functions. If a |
| 533 function is overloaded, the handle determines at the time of its | |
| 534 reference which function to call. A non-overloaded version does not | |
| 535 need to exist. | |
| 9873 | 536 |
| 10118 | 537 ** Overloading functions for built-in classes (double, int8, cell, |
| 538 etc.) is now compatible with Matlab. | |
| 9408 | 539 |
| 10323 | 540 ** Function handles can now be compared with the == and != operators, |
| 541 as well as the `isequal' function. | |
| 542 | |
| 10118 | 543 ** Performance of concatenation (using []) and the functions `cat', |
| 544 `horzcat', and `vertcat' has been improved for multidimensional | |
| 545 arrays. | |
| 10117 | 546 |
| 9547 | 547 ** The operation-assignment operators +=, -=, *= and /= now behave more |
| 10118 | 548 efficiently in certain cases. For instance, if M is a matrix and S a |
| 549 scalar, then the statement | |
| 9547 | 550 |
| 10118 | 551 M += S; |
| 9547 | 552 |
| 10118 | 553 will operate on M's data in-place if it is not shared by another |
| 554 variable, usually increasing both time and memory efficiency. | |
| 9547 | 555 |
| 9558 | 556 Only selected common combinations are affected, namely: |
| 9547 | 557 |
| 558 matrix += matrix | |
| 559 matrix -= matrix | |
| 9558 | 560 matrix .*= matrix |
| 561 matrix ./= matrix | |
| 562 | |
| 9547 | 563 matrix += scalar |
| 564 matrix -= scalar | |
| 565 matrix *= scalar | |
| 566 matrix /= scalar | |
| 9558 | 567 |
| 9552 | 568 logical matrix |= logical matrix |
| 569 logical matrix &= logical matrix | |
| 9547 | 570 |
| 10118 | 571 where matrix and scalar belong to the same class. The left-hand |
| 572 side must be a simple variable reference. | |
| 9888 | 573 |
| 10118 | 574 Moreover, when unary operators occur in expressions, Octave will |
| 575 also try to do the operation in-place if it's argument is a | |

576 temporary expression. |
| 9589 | 577 |
| 10118 | 578 ** The effect of comparison operators (<, >, <=, and >=) applied to |
| 579 complex numbers has changed to be consistent with the strict | |
| 580 ordering defined by the `max', `min', and `sort' functions. More | |
| 581 specifically, complex numbers are compared by lexicographical | |
| 582 comparison of the pairs `[abs(z), arg(z)]'. Previously, only real | |
| 14188 | 583 parts were compared; this can be trivially achieved by converting |
| 584 the operands to real values with the `real' function. | |
| 9547 | 585 |
| 10118 | 586 ** The automatic simplification of complex computation results has |
| 587 changed. Octave will now simplify any complex number with a zero | |
| 588 imaginary part or any complex matrix with all elements having zero | |
| 589 imaginary part to a real value. Previously, this was done only for | |
| 590 positive zeros. Note that the behavior of the complex function is | |
| 591 unchanged and it still produces a complex value even if the | |
| 592 imaginary part is zero. | |
| 9826 | 593 |
| 10118 | 594 ** As a side effect of code refactoring in liboctave, the binary |
| 595 logical operations are now more easily amenable to compiler | |
| 596 optimizations and are thus significantly faster. | |
| 9595 | 597 |
| 10118 | 598 ** Octave now allows user-defined `subsasgn' methods to optimize out |
| 599 redundant copies. For more information, see the manual. | |
| 9595 | 600 |

| 10118 | 602 handle the expressions |

606 V / M |
| 9664 | 607 |
| 10118 | 608 (M is a matrix and V is a vector) more efficiently in certain cases. |
| 609 In particular, if M is triangular, all three expressions will be | |
| 610 handled by a single call to xTRTRS (from LAPACK), with appropriate | |
| 10453 | 611 flags. Previously, all three expressions required a physical |
| 10118 | 612 transpose of M. |
| 9664 | 613 |
| 10118 | 614 ** More efficient handling of certain mixed real-complex matrix |
| 615 operations. For instance, if RM is a real matrix and CM a complex | |
| 616 matrix, | |
| 9664 | 617 |
| 10118 | 618 RM * CM |
| 9664 | 619 |
| 620 can now be evaluated either as | |
| 621 | |
| 622 complex (RM * real (CM), RM * imag (CM)) | |
| 623 | |
| 624 or as | |
| 625 | |
| 626 complex (RM) * CM, | |
| 627 | |
| 10453 | 628 depending on the dimensions. The first form requires more |
| 629 temporaries and copying, but halves the FLOP count, which normally | |
| 630 brings better performance if RM has enough rows. Previously, the | |
| 631 second form was always used. | |
| 9664 | 632 |
| 11111 | 633 Matrix division is similarly affected. |
| 9664 | 634 |
| 10118 | 635 ** More efficient handling of triangular matrix factors returned from |
| 636 factorizations. The functions for computing QR, LU and Cholesky | |
| 637 factorizations will now automatically return the triangular matrix | |
| 638 factors with proper internal matrix_type set, so that it won't need | |
| 639 to be computed when the matrix is used for division. | |
| 9717 | 640 |
| 10118 | 641 ** The built-in `sum' function now handles the non-native summation |
| 642 (i.e., double precision sum of single or integer inputs) more | |
| 643 efficiently, avoiding a temporary conversion of the whole input | |
| 644 array to doubles. Further, `sum' can now accept an extra option | |
| 645 argument, using a compensated summation algorithm rather than a | |
| 646 straightforward sum, which significantly improves precision if lots | |
| 647 of cancellation occurs in the summation. | |
| 9717 | 648 |
| 10118 | 649 ** The built-in `bsxfun' function now uses optimized code for certain |
| 650 cases where built-in operator handles are passed in. Namely, the | |
| 651 optimizations concern the operators `plus', `minus', `times', | |
| 652 `ldivide', `rdivide', `power', `and', `or' (for logical arrays), | |
| 653 the relational operators `eq', `ne', `lt', `le', `gt', `ge', and the | |
| 654 functions `min' and `max'. Optimizations only apply when both | |
| 655 operands are of the same built-in class. Mixed real/complex and | |
| 656 single/double operations will first convert both operands to a | |
| 657 common type. | |
| 9745 | 658 |
| 10118 | 659 ** The `strfind' and `strrep' functions now have compiled |
| 660 implementations, facilitating significantly more efficient searching | |
| 661 and replacing in strings, especially with longer patterns. The code | |
| 662 of `strcat' has been vectorized and is now much more efficient when | |
| 663 many strings are concatenated. The `strcmpi' and `strncmpi' | |
| 664 functions are now built-in functions, providing better performance. | |

669 has been removed. |

| 10453 | 671 ** Matlab-style ignoring input and output function arguments using |
| 11111 | 672 tilde (~) is now supported. Ignored output arguments may be |
| 673 detected from a function using the built-in function `isargout'. | |
| 674 For more details, consult the manual. | |
| 10886 | 675 |
| 10453 | 676 ** The list datatype, deprecated since the introduction of cells, has |
| 677 been removed. | |
| 10276 | 678 |
| 10453 | 679 ** The accumarray function has been optimized and is now significantly |
| 680 faster in certain important cases. | |
| 10054 | 681 |
| 10292 | 682 ** The behavior of isreal and isnumeric functions was changed to be more |
| 683 Matlab-compatible. | |
| 684 | |
| 10406 | 685 ** The integer math & conversion warnings (Octave:int-convert-nan, |
| 686 Octave:int-convert-non-int-val, Octave:int-convert-overflow, | |
| 11111 | 687 Octave:int-math-overflow) have been removed. |
| 10406 | 688 |
| 10453 | 689 ** rem and mod are now built-in functions. They also handle integer |
| 690 types efficiently using integer arithmetic. | |
| 10437 | 691 |
| 10536 | 692 ** Sparse indexing and indexed assignment has been mostly rewritten. |
| 693 Since Octave uses compressed column storage for sparse matrices, | |
| 694 major attention is devoted to operations manipulating whole columns. | |
| 695 Such operations are now significantly faster, as well as some other | |
| 696 important cases. | |
| 697 | |
| 698 Further, it is now possible to pre-allocate a sparse matrix and | |
| 699 subsequently fill it by assignments, provided they meet certain | |
| 700 conditions. For more information, consult the `spalloc' function, | |
| 701 which is no longer a mere dummy. Consequently, nzmax and nnz are no | |
| 11111 | 702 longer always equal in Octave. Octave may also produce a matrix |
| 703 with nnz < nzmax as a result of other operations, so you should | |

704 consistently use nnz unless you really want to use nzmax (i.e., the |
| 11111 | 705 space allocated for nonzero elements). |
| 10536 | 706 |
| 707 Sparse concatenation is also affected, and concatenating sparse | |
| 708 matrices, especially larger collections, is now significantly more | |
| 11111 | 709 efficient. This applies to both the [] operator and the |
| 10536 | 710 cat/vertcat/horzcat functions. |
| 711 | |
| 11111 | 712 ** It is now possible to optionally employ the xGESDD LAPACK drivers |
| 14188 | 713 for computing the singular value decomposition using svd, instead |
| 11111 | 714 of the default xGESVD, using the configuration pseudo-variable |
| 715 svd_driver. The xGESDD driver can be up to 6x times faster when | |
| 716 singular vectors are requested, but is reported to be somewhat less | |
| 10639 | 717 robust on highly ill-conditioned matrices. |
| 718 | |
| 719 ** Configuration pseudo-variables, such as page_screen_output or | |
| 720 confirm_recursive_rmdir (or the above mentioned svd_driver), now | |
| 721 accept a "local" option as second argument, requesting the change | |

935 __gnuplot_show__, __gnuplot_replot__, __gnuplot_splot__, |
| 8737 | 936 __gnuplot_save_data__ and __gnuplot_send_inline_data__ have been |
| 937 removed from Octave. These function were incompatible with the | |
| 938 high level graphics handle code. | |
| 6329 | 939 |
| 8885 | 940 ** The Control, Finance and Quaternion functions have been removed. |
| 941 | |
| 942 These functions are now available as separate packages from | |
| 943 | |
| 944 http://octave.sourceforge.net/packages.html | |
| 945 | |
| 946 and can be reinstalled using the Octave package manager (see | |
| 947 the pkg function). | |
| 948 | |
| 949 ** Specific sparse matrix functions removed. | |
| 950 | |
| 951 The following functions, which handled only sparse matrices have | |
| 952 been removed. Instead of calling these functions directly, you | |
| 953 should use the corresponding function without the "sp" prefix. | |
| 8737 | 954 |

| 959 spcumprod spinv spmin | |
| 960 | |
| 961 ** Improvements to the debugger. | |
| 962 | |
| 963 The interactive debugging features have been improved. Stopping | |
| 964 on statements with dbstop should work correctly now. Stepping | |
| 965 into and over functions, and stepping one statement at a time | |
| 966 (with dbstep) now works. Moving up and down the call stack with | |
| 967 dbup and dbdown now works. The dbstack function is now available | |
| 968 to print the current function call stack. The new dbquit function | |
| 969 is available to exit the debugging mode. | |
| 970 | |
| 971 ** Improved traceback error messages. | |
| 972 | |
| 973 Traceback error messages are much more concise and easier to | |
| 974 understand. They now display information about the function call | |
| 975 stack instead of the stack of all statements that were active at | |
| 976 the point of the error. | |

979 |
| 8737 | 980 Octave now includes OOP features and the user can create their own |
| 981 class objects and overloaded functions and operators. For | |
| 982 example, all methods of a class called "myclass" will be found in | |
| 983 a directory "@myclass" on the users path. The class specific | |
| 984 versions of functions and operators take precedence over the | |
| 985 generic versions of these functions. | |
| 986 | |
| 987 New functions related to OOP include | |
| 7189 | 988 |
| 8737 | 989 class inferiorto isobject loadobj methods superiorto |
| 990 | |
| 991 See the Octave manual for more details. | |
| 7038 | 992 |
| 8747 | 993 ** Parsing of Command-style Functions. |
| 994 | |
| 995 Octave now parses command-style functions without needing to first | |
| 996 declare them with "mark_as_command". The rules for recognizing a | |
| 997 command-style function calls are | |
| 998 | |
| 999 * A command must appear as the first word in a statement, | |
| 1000 followed by a space. | |
| 1001 | |
| 1002 * The first character after the space must not be '=' or '(' | |
| 1003 | |
| 1004 * The next token after the space must not look like a binary | |
| 1005 operator. | |
| 1006 | |
| 1007 These rules should be mostly compatible with the way Matlab parses | |
| 1008 command-style function calls and allow users to define commands in | |
| 1009 .m files without having to mark them as commands. | |
| 1010 | |
| 1011 Note that previous versions of Octave allowed expressions like | |
| 1012 | |
| 1013 x = load -text foo.dat | |
| 1014 | |
| 1015 but an expression like this will now generate a parse error. In | |
| 1016 order to assign the value returned by a function to a variable, | |
| 1017 you must use the normal function call syntax: | |
| 1018 | |
| 1019 x = load ("-text", "foo.dat"); | |
| 1020 | |
| 8737 | 1021 ** Block comments. |
| 1022 | |
| 8747 | 1023 Commented code can be between matching "#{" and "#}" or "%{" and |

1089 conversions between cells, structs and cs-lists. This usually reduces |
| 8755 | 1090 both time and memory consumption. |

1114 subtracting a scalar, and multiplying by a scalar. Ranges with zero |
| 10453 | 1115 increment are allowed and can be constructed using the built-in |
| 1116 function `ones'. | |
| 9006 | 1117 |
| 1118 ** Various performance improvements. | |
| 1119 | |
| 10453 | 1120 Performance of a number of other built-in operations and functions |
| 1121 was improved, including: | |
| 9006 | 1122 |
| 1123 * logical operations | |
| 1124 * comparison operators | |
| 1125 * element-wise power | |
| 1126 * accumarray | |
| 1127 * cellfun | |
| 1128 * isnan | |
| 1129 * isinf | |
| 1130 * isfinite | |
| 1131 * nchoosek | |
| 1132 * repmat | |
| 1133 * strcmp | |
| 1134 | |
| 8737 | 1135 ** 64-bit integer arithmetic. |
| 1136 | |
| 1137 Arithmetic with 64-bit integers (int64 and uint64 types) is fully | |
| 1138 supported, with saturation semantics like the other integer types. | |
| 1139 Performance of most integer arithmetic operations has been | |
| 1140 improved by using integer arithmetic directly. Previously, Octave | |
| 1141 performed integer math with saturation semantics by converting the | |
| 1142 operands to double precision, performing the operation, and then | |
| 1143 converting the result back to an integer value, truncating if | |
| 1144 necessary. | |
| 1145 | |
| 8885 | 1146 ** Diagonal and permutation matrices. |
| 1147 | |
| 1148 The interpreter can now treat diagonal and permutation matrices as | |
| 1149 special objects that store only the non-zero elements, rather than | |
| 1150 general full matrices. Therefore, it is now possible to construct | |
| 1151 and use these matrices in linear algebra without suffering a | |
| 1152 performance penalty due to storing large numbers of zero elements. | |
| 1153 | |
| 1154 ** Improvements to fsolve. | |
| 1155 | |
| 1156 The fsolve function now accepts an option structure argument (see | |
| 1157 also the optimset function). The INFO values returned from fsolve | |
| 1158 have changed to be compatible with Matlab's fsolve function. | |
| 1159 Additionally, fsolve is now able to solve overdetermined systems, | |
| 1160 complex-differentiable complex systems, systems with a sparse | |
| 1161 jacobian and can work in single precision if given single precision | |

| 1167 matrix in a single call, as well as general matrix p-norms. | |
| 1168 | |
| 1169 ** New functions for computing some eigenvalues or singular values. | |
| 1170 | |
| 1171 The eigs and svds functions have been included in Octave. These | |
| 1172 functions require the ARPACK library (now distributed under a | |
