539 |
| 10118 | 540 ** The `lookup' function was extended to be more useful for |
| 541 general-purpose binary searching. Using this improvement, the | |
| 542 ismember function was rewritten for significantly better | |
| 543 performance. | |
| 9352 | 544 |
| 545 ** Real, integer and logical matrices, when used in indexing, will now | |
| 546 cache the internal index_vector value (zero-based indices) when | |
| 547 successfully used as indices, eliminating the conversion penalty for | |
| 10118 | 548 subsequent indexing by the same matrix. In particular, this means it |
| 549 is no longer needed to avoid repeated indexing by logical arrays | |
| 550 using find for performance reasons. | |
| 9888 | 551 |
| 10118 | 552 ** Logical matrices are now treated more efficiently when used as |
| 553 indices. Octave will keep the index as a logical mask unless the | |
| 554 ratio of true elements is small enough, using a specialized | |
| 555 code. Previously, all logical matrices were always first converted | |
| 556 to index vectors. This results in savings in both memory and | |
| 557 computing time. | |
| 9480 | 558 |
| 10118 | 559 ** The `sub2ind' and `ind2sub' functions were reimplemented as compiled |
| 560 functions for better performance. These functions are now faster, | |
| 561 can deliver more economized results for ranges, and can reuse the | |
| 562 index cache mechanism described in previous paragraph. | |
| 563 | |
| 564 ** The built-in function equivalents to associative operators (`plus', | |
| 565 `times', `mtimes', `and', and `or') have been extended to accept | |
| 566 multiple arguments. This is especially useful for summing | |
| 567 (multiplying, etc.) lists of objects (of possibly distinct types): | |
| 9408 | 568 |
| 9449 | 569 matrix_sum = plus (matrix_list{:}); |
| 570 | |
| 10118 | 571 ** An FTP object type based on libcurl has been implemented. These |
| 572 objects allow ftp connections, downloads and uploads to be | |
| 573 managed. For example, | |
| 9880 | 574 |
| 10118 | 575 fp = ftp ("ftp.octave.org); |
| 576 cd (fp, "gnu/octave"); | |
| 577 mget (fp, "octave-3.2.3.tar.bz2"); | |
| 578 close (fp); | |
| 9880 | 579 |
| 10118 | 580 ** The default behavior of `assert (observed, expected)' has been |
| 581 relaxed to employ less strict checking that does not require the | |
| 582 internals of the values to match. This avoids previously valid | |
| 583 tests from breaking due to new internal classes introduced in future | |
| 584 Octave versions. | |
| 9449 | 585 |
| 586 For instance, all of these assertions were true in Octave 3.0.x | |
| 587 but false in 3.2.x due to new optimizations and improvements: | |
| 588 | |
| 589 assert (2*linspace (1, 5, 5), 2*(1:5)) | |
| 590 assert (zeros (0, 0), []) | |
| 591 assert (2*ones (1, 5), (2) (ones (1,5))) | |
| 9462 | 592 |
| 10118 | 593 ** The behavior of library functions `ismatrix', `issquare', and |
| 594 `issymmetric' has been changed for better consistency. | |
| 9873 | 595 |
| 10292 | 596 * The `ismatrix' function now returns true for all numeric, |

597 logical and character 2-D or N-D matrices. Previously, `ismatrix' |
| 10292 | 598 returned false if the first or second dimension was zero. |
| 599 Hence, `ismatrix ([])' was false, | |
| 600 while `ismatrix (zeros (1,2,0))' was true. | |
| 9873 | 601 |
| 10118 | 602 * The `issquare' function now returns a logical scalar, and is |
| 603 equivalent to the expression | |
| 604 | |
| 605 ismatrix (x) && ndims (x) == 2 && rows (x) == columns (x) | |
| 606 | |
| 607 The dimension is no longer returned. As a result, `issquare ([])' | |
| 608 now yields true. | |
| 9873 | 609 |
| 10118 | 610 * The `issymmetric' function now checks for symmetry instead of |

611 Hermitianness. For the latter, ishermitian was created. Also, |
| 10118 | 612 logical scalar is returned rather than the dimension, so |
| 613 `issymmetric ([])' is now true. | |
| 9873 | 614 |
| 10118 | 615 ** Function handles are now aware of overloaded functions. If a |
| 616 function is overloaded, the handle determines at the time of its | |
| 617 reference which function to call. A non-overloaded version does not | |
| 618 need to exist. | |
| 9873 | 619 |
| 10118 | 620 ** Overloading functions for built-in classes (double, int8, cell, |
| 621 etc.) is now compatible with Matlab. | |
| 9408 | 622 |
| 10323 | 623 ** Function handles can now be compared with the == and != operators, |
| 624 as well as the `isequal' function. | |
| 625 | |
| 10118 | 626 ** Performance of concatenation (using []) and the functions `cat', |
| 627 `horzcat', and `vertcat' has been improved for multidimensional | |
| 628 arrays. | |
| 10117 | 629 |
| 9547 | 630 ** The operation-assignment operators +=, -=, *= and /= now behave more |
| 10118 | 631 efficiently in certain cases. For instance, if M is a matrix and S a |
| 632 scalar, then the statement | |
| 9547 | 633 |
| 10118 | 634 M += S; |
| 9547 | 635 |
| 10118 | 636 will operate on M's data in-place if it is not shared by another |
| 637 variable, usually increasing both time and memory efficiency. | |
| 9547 | 638 |
| 9558 | 639 Only selected common combinations are affected, namely: |
| 9547 | 640 |
| 641 matrix += matrix | |
| 642 matrix -= matrix | |
| 9558 | 643 matrix .*= matrix |
| 644 matrix ./= matrix | |
| 645 | |
| 9547 | 646 matrix += scalar |
| 647 matrix -= scalar | |
| 648 matrix *= scalar | |
| 649 matrix /= scalar | |
| 9558 | 650 |
| 9552 | 651 logical matrix |= logical matrix |
| 652 logical matrix &= logical matrix | |
| 9547 | 653 |
| 10118 | 654 where matrix and scalar belong to the same class. The left-hand |
| 655 side must be a simple variable reference. | |
| 9888 | 656 |
| 10118 | 657 Moreover, when unary operators occur in expressions, Octave will |
| 658 also try to do the operation in-place if it's argument is a | |

659 temporary expression. |
| 9589 | 660 |
| 10118 | 661 ** The effect of comparison operators (<, >, <=, and >=) applied to |
| 662 complex numbers has changed to be consistent with the strict | |
| 663 ordering defined by the `max', `min', and `sort' functions. More | |
| 664 specifically, complex numbers are compared by lexicographical | |
| 665 comparison of the pairs `[abs(z), arg(z)]'. Previously, only real | |
| 14188 | 666 parts were compared; this can be trivially achieved by converting |
| 667 the operands to real values with the `real' function. | |
| 9547 | 668 |
| 10118 | 669 ** The automatic simplification of complex computation results has |
| 670 changed. Octave will now simplify any complex number with a zero | |
| 671 imaginary part or any complex matrix with all elements having zero | |
| 672 imaginary part to a real value. Previously, this was done only for | |
| 673 positive zeros. Note that the behavior of the complex function is | |
| 674 unchanged and it still produces a complex value even if the | |
| 675 imaginary part is zero. | |
| 9826 | 676 |
| 10118 | 677 ** As a side effect of code refactoring in liboctave, the binary |
| 678 logical operations are now more easily amenable to compiler | |
| 679 optimizations and are thus significantly faster. | |
| 9595 | 680 |
| 10118 | 681 ** Octave now allows user-defined `subsasgn' methods to optimize out |
| 682 redundant copies. For more information, see the manual. | |
| 9595 | 683 |
| 10453 | 684 ** More efficient matrix division handling. Octave is now able to |
| 10118 | 685 handle the expressions |

689 V / M |
| 9664 | 690 |
| 10118 | 691 (M is a matrix and V is a vector) more efficiently in certain cases. |
| 692 In particular, if M is triangular, all three expressions will be | |
| 693 handled by a single call to xTRTRS (from LAPACK), with appropriate | |
| 10453 | 694 flags. Previously, all three expressions required a physical |
| 10118 | 695 transpose of M. |
| 9664 | 696 |
| 10118 | 697 ** More efficient handling of certain mixed real-complex matrix |
| 698 operations. For instance, if RM is a real matrix and CM a complex | |
| 699 matrix, | |
| 9664 | 700 |
| 10118 | 701 RM * CM |
| 9664 | 702 |
| 703 can now be evaluated either as | |
| 704 | |
| 705 complex (RM * real (CM), RM * imag (CM)) | |
| 706 | |
| 707 or as | |
| 708 | |
| 709 complex (RM) * CM, | |
| 710 | |
| 10453 | 711 depending on the dimensions. The first form requires more |
| 712 temporaries and copying, but halves the FLOP count, which normally | |
| 713 brings better performance if RM has enough rows. Previously, the | |
| 714 second form was always used. | |
| 9664 | 715 |
| 11111 | 716 Matrix division is similarly affected. |
| 9664 | 717 |
| 10118 | 718 ** More efficient handling of triangular matrix factors returned from |
| 719 factorizations. The functions for computing QR, LU and Cholesky | |
| 720 factorizations will now automatically return the triangular matrix | |
| 721 factors with proper internal matrix_type set, so that it won't need | |
| 722 to be computed when the matrix is used for division. | |
| 9717 | 723 |
| 10118 | 724 ** The built-in `sum' function now handles the non-native summation |
| 725 (i.e., double precision sum of single or integer inputs) more | |
| 726 efficiently, avoiding a temporary conversion of the whole input | |
| 727 array to doubles. Further, `sum' can now accept an extra option | |
| 728 argument, using a compensated summation algorithm rather than a | |
| 729 straightforward sum, which significantly improves precision if lots | |
| 730 of cancellation occurs in the summation. | |
| 9717 | 731 |
| 10118 | 732 ** The built-in `bsxfun' function now uses optimized code for certain |
| 733 cases where built-in operator handles are passed in. Namely, the | |
| 734 optimizations concern the operators `plus', `minus', `times', | |
| 735 `ldivide', `rdivide', `power', `and', `or' (for logical arrays), | |
| 736 the relational operators `eq', `ne', `lt', `le', `gt', `ge', and the | |
| 737 functions `min' and `max'. Optimizations only apply when both | |
| 738 operands are of the same built-in class. Mixed real/complex and | |
| 739 single/double operations will first convert both operands to a | |
| 740 common type. | |
| 9745 | 741 |
| 10118 | 742 ** The `strfind' and `strrep' functions now have compiled |
| 743 implementations, facilitating significantly more efficient searching | |
| 744 and replacing in strings, especially with longer patterns. The code | |
| 745 of `strcat' has been vectorized and is now much more efficient when | |
| 746 many strings are concatenated. The `strcmpi' and `strncmpi' | |
| 747 functions are now built-in functions, providing better performance. | |

752 has been removed. |
| 10208 | 753 |
| 10453 | 754 ** Matlab-style ignoring input and output function arguments using |
| 11111 | 755 tilde (~) is now supported. Ignored output arguments may be |
| 756 detected from a function using the built-in function `isargout'. | |
| 757 For more details, consult the manual. | |
| 10886 | 758 |
| 10453 | 759 ** The list datatype, deprecated since the introduction of cells, has |
| 760 been removed. | |
| 10276 | 761 |
| 10453 | 762 ** The accumarray function has been optimized and is now significantly |
| 763 faster in certain important cases. | |
| 10054 | 764 |
| 10292 | 765 ** The behavior of isreal and isnumeric functions was changed to be more |
| 766 Matlab-compatible. | |
| 767 | |
| 10406 | 768 ** The integer math & conversion warnings (Octave:int-convert-nan, |
| 769 Octave:int-convert-non-int-val, Octave:int-convert-overflow, | |
| 11111 | 770 Octave:int-math-overflow) have been removed. |
| 10406 | 771 |
| 10453 | 772 ** rem and mod are now built-in functions. They also handle integer |
| 773 types efficiently using integer arithmetic. | |
| 10437 | 774 |
| 10536 | 775 ** Sparse indexing and indexed assignment has been mostly rewritten. |
| 776 Since Octave uses compressed column storage for sparse matrices, | |
| 777 major attention is devoted to operations manipulating whole columns. | |
| 778 Such operations are now significantly faster, as well as some other | |
| 779 important cases. | |
| 780 | |
| 781 Further, it is now possible to pre-allocate a sparse matrix and | |
| 782 subsequently fill it by assignments, provided they meet certain | |
| 783 conditions. For more information, consult the `spalloc' function, | |
| 784 which is no longer a mere dummy. Consequently, nzmax and nnz are no | |
| 11111 | 785 longer always equal in Octave. Octave may also produce a matrix |
| 786 with nnz < nzmax as a result of other operations, so you should | |

787 consistently use nnz unless you really want to use nzmax (i.e., the |
| 11111 | 788 space allocated for nonzero elements). |
| 10536 | 789 |
| 790 Sparse concatenation is also affected, and concatenating sparse | |
| 791 matrices, especially larger collections, is now significantly more | |
| 11111 | 792 efficient. This applies to both the [] operator and the |
| 10536 | 793 cat/vertcat/horzcat functions. |
| 794 | |
| 11111 | 795 ** It is now possible to optionally employ the xGESDD LAPACK drivers |
| 14188 | 796 for computing the singular value decomposition using svd, instead |
| 11111 | 797 of the default xGESVD, using the configuration pseudo-variable |
| 798 svd_driver. The xGESDD driver can be up to 6x times faster when | |
| 799 singular vectors are requested, but is reported to be somewhat less | |
| 10639 | 800 robust on highly ill-conditioned matrices. |
| 801 | |
| 802 ** Configuration pseudo-variables, such as page_screen_output or | |
| 803 confirm_recursive_rmdir (or the above mentioned svd_driver), now | |
| 804 accept a "local" option as second argument, requesting the change | |

| 8737 | 1019 __gnuplot_save_data__ and __gnuplot_send_inline_data__ have been |
| 1020 removed from Octave. These function were incompatible with the | |

| 6329 | 1022 |
| 8885 | 1023 ** The Control, Finance and Quaternion functions have been removed. |

| 1025 These functions are now available as separate packages from | |

| 1027 http://octave.sourceforge.net/packages.html | |
| 1028 | |
| 1029 and can be reinstalled using the Octave package manager (see | |
| 1030 the pkg function). | |
| 1031 | |
| 1032 ** Specific sparse matrix functions removed. | |
| 1033 | |
| 1034 The following functions, which handled only sparse matrices have | |
| 1035 been removed. Instead of calling these functions directly, you | |
| 1036 should use the corresponding function without the "sp" prefix. | |

| 1043 | |
| 1044 ** Improvements to the debugger. | |
| 1045 | |
| 1046 The interactive debugging features have been improved. Stopping | |
| 1047 on statements with dbstop should work correctly now. Stepping | |
| 1048 into and over functions, and stepping one statement at a time | |
| 1049 (with dbstep) now works. Moving up and down the call stack with | |
| 1050 dbup and dbdown now works. The dbstack function is now available | |
| 1051 to print the current function call stack. The new dbquit function | |
| 1052 is available to exit the debugging mode. | |
| 1053 | |
| 1054 ** Improved traceback error messages. | |
| 1055 | |
| 1056 Traceback error messages are much more concise and easier to | |
| 1057 understand. They now display information about the function call | |
| 1058 stack instead of the stack of all statements that were active at | |
| 1059 the point of the error. | |

1062 |
| 8737 | 1063 Octave now includes OOP features and the user can create their own |
| 1064 class objects and overloaded functions and operators. For | |
| 1065 example, all methods of a class called "myclass" will be found in | |
| 1066 a directory "@myclass" on the users path. The class specific | |
| 1067 versions of functions and operators take precedence over the | |
| 1068 generic versions of these functions. | |
| 1069 | |
| 1070 New functions related to OOP include | |
| 7189 | 1071 |
| 8737 | 1072 class inferiorto isobject loadobj methods superiorto |
| 1073 | |
| 1074 See the Octave manual for more details. | |
| 7038 | 1075 |
| 8747 | 1076 ** Parsing of Command-style Functions. |
| 1077 | |
| 1078 Octave now parses command-style functions without needing to first | |
| 1079 declare them with "mark_as_command". The rules for recognizing a | |
| 1080 command-style function calls are | |
| 1081 | |
| 1082 * A command must appear as the first word in a statement, | |
| 1083 followed by a space. | |
| 1084 | |
| 1085 * The first character after the space must not be '=' or '(' | |
| 1086 | |
| 1087 * The next token after the space must not look like a binary | |
| 1088 operator. | |
| 1089 | |
| 1090 These rules should be mostly compatible with the way Matlab parses | |
| 1091 command-style function calls and allow users to define commands in | |
| 1092 .m files without having to mark them as commands. | |
| 1093 | |
| 1094 Note that previous versions of Octave allowed expressions like | |
| 1095 | |
| 1096 x = load -text foo.dat | |
| 1097 | |
| 1098 but an expression like this will now generate a parse error. In | |
| 1099 order to assign the value returned by a function to a variable, | |
| 1100 you must use the normal function call syntax: | |
| 1101 | |
| 1102 x = load ("-text", "foo.dat"); | |
| 1103 | |
| 8737 | 1104 ** Block comments. |
| 1105 | |
| 8747 | 1106 Commented code can be between matching "#{" and "#}" or "%{" and |
| 1107 "%}" markers, even if the commented code spans several line. This | |
| 1108 allows blocks code to be commented, without needing to comment | |
| 1109 each line. For example, | |
| 5814 | 1110 |
| 8747 | 1111 function [s, t] = func (x, y) |
| 1112 s = 2 * x; | |
| 1113 #{ | |
| 1114 s *= y; | |
| 1115 t = y + x; | |
| 1116 #} | |

1172 conversions between cells, structs and cs-lists. This usually reduces |
| 8755 | 1173 both time and memory consumption. |
| 9128 | 1174 Also, Octave will now attempt to detect and optimize usage of a vector |
| 1175 as a stack, when elements are being repeatedly inserted at/removed from | |
| 1176 the end of the vector. | |
| 8755 | 1177 |

1188 efficient algorithm, especially in the homogeneous case. The lookup |

1197 subtracting a scalar, and multiplying by a scalar. Ranges with zero |
| 10453 | 1198 increment are allowed and can be constructed using the built-in |
| 1199 function `ones'. | |
| 9006 | 1200 |
| 1201 ** Various performance improvements. | |
| 1202 | |
| 10453 | 1203 Performance of a number of other built-in operations and functions |
| 1204 was improved, including: | |
| 9006 | 1205 |
| 1206 * logical operations | |
| 1207 * comparison operators | |
| 1208 * element-wise power | |
| 1209 * accumarray | |
| 1210 * cellfun | |
| 1211 * isnan | |
| 1212 * isinf | |
| 1213 * isfinite | |
| 1214 * nchoosek | |
| 1215 * repmat | |
| 1216 * strcmp | |
| 1217 | |
| 8737 | 1218 ** 64-bit integer arithmetic. |
| 1219 | |
| 1220 Arithmetic with 64-bit integers (int64 and uint64 types) is fully | |
| 1221 supported, with saturation semantics like the other integer types. | |
| 1222 Performance of most integer arithmetic operations has been | |
| 1223 improved by using integer arithmetic directly. Previously, Octave | |
| 1224 performed integer math with saturation semantics by converting the | |
| 1225 operands to double precision, performing the operation, and then | |
| 1226 converting the result back to an integer value, truncating if | |
| 1227 necessary. | |
| 1228 | |
| 8885 | 1229 ** Diagonal and permutation matrices. |
| 1230 | |
| 1231 The interpreter can now treat diagonal and permutation matrices as | |
| 1232 special objects that store only the non-zero elements, rather than | |
| 1233 general full matrices. Therefore, it is now possible to construct | |
| 1234 and use these matrices in linear algebra without suffering a | |
| 1235 performance penalty due to storing large numbers of zero elements. | |
| 1236 | |
| 1237 ** Improvements to fsolve. | |
| 1238 | |
| 1239 The fsolve function now accepts an option structure argument (see | |
| 1240 also the optimset function). The INFO values returned from fsolve | |
| 1241 have changed to be compatible with Matlab's fsolve function. | |
| 1242 Additionally, fsolve is now able to solve overdetermined systems, | |
| 1243 complex-differentiable complex systems, systems with a sparse | |
| 1244 jacobian and can work in single precision if given single precision | |

| 8885 | 1246 |

| 1248 | |
| 1249 The norm function is now able to compute row or column norms of a | |
| 1250 matrix in a single call, as well as general matrix p-norms. | |
| 1251 | |
| 1252 ** New functions for computing some eigenvalues or singular values. | |
| 1253 | |
| 1254 The eigs and svds functions have been included in Octave. These | |
| 1255 functions require the ARPACK library (now distributed under a | |
| 1256 GPL-compatible license). | |
| 1257 | |
