354 |
| 10118 | 355 ** The `lookup' function was extended to be more useful for |
| 356 general-purpose binary searching. Using this improvement, the | |
| 357 ismember function was rewritten for significantly better | |
| 358 performance. | |
| 9352 | 359 |
| 360 ** Real, integer and logical matrices, when used in indexing, will now | |
| 361 cache the internal index_vector value (zero-based indices) when | |
| 362 successfully used as indices, eliminating the conversion penalty for | |
| 10118 | 363 subsequent indexing by the same matrix. In particular, this means it |
| 364 is no longer needed to avoid repeated indexing by logical arrays | |
| 365 using find for performance reasons. | |
| 9888 | 366 |
| 10118 | 367 ** Logical matrices are now treated more efficiently when used as |
| 368 indices. Octave will keep the index as a logical mask unless the | |
| 369 ratio of true elements is small enough, using a specialized | |
| 370 code. Previously, all logical matrices were always first converted | |
| 371 to index vectors. This results in savings in both memory and | |
| 372 computing time. | |
| 9480 | 373 |
| 10118 | 374 ** The `sub2ind' and `ind2sub' functions were reimplemented as compiled |
| 375 functions for better performance. These functions are now faster, | |
| 376 can deliver more economized results for ranges, and can reuse the | |
| 377 index cache mechanism described in previous paragraph. | |
| 378 | |
| 379 ** The built-in function equivalents to associative operators (`plus', | |
| 380 `times', `mtimes', `and', and `or') have been extended to accept | |
| 381 multiple arguments. This is especially useful for summing | |
| 382 (multiplying, etc.) lists of objects (of possibly distinct types): | |
| 9408 | 383 |
| 9449 | 384 matrix_sum = plus (matrix_list{:}); |
| 385 | |
| 10118 | 386 ** An FTP object type based on libcurl has been implemented. These |
| 387 objects allow ftp connections, downloads and uploads to be | |
| 388 managed. For example, | |
| 9880 | 389 |
| 10118 | 390 fp = ftp ("ftp.octave.org); |
| 391 cd (fp, "gnu/octave"); | |
| 392 mget (fp, "octave-3.2.3.tar.bz2"); | |
| 393 close (fp); | |
| 9880 | 394 |
| 10118 | 395 ** The default behavior of `assert (observed, expected)' has been |
| 396 relaxed to employ less strict checking that does not require the | |
| 397 internals of the values to match. This avoids previously valid | |
| 398 tests from breaking due to new internal classes introduced in future | |
| 399 Octave versions. | |
| 9449 | 400 |
| 401 For instance, all of these assertions were true in Octave 3.0.x | |
| 402 but false in 3.2.x due to new optimizations and improvements: | |
| 403 | |
| 404 assert (2*linspace (1, 5, 5), 2*(1:5)) | |
| 405 assert (zeros (0, 0), []) | |
| 406 assert (2*ones (1, 5), (2) (ones (1,5))) | |
| 9462 | 407 |
| 10118 | 408 ** The behavior of library functions `ismatrix', `issquare', and |
| 409 `issymmetric' has been changed for better consistency. | |
| 9873 | 410 |
| 10292 | 411 * The `ismatrix' function now returns true for all numeric, |

412 logical and character 2-D or N-D matrices. Previously, `ismatrix' |
| 10292 | 413 returned false if the first or second dimension was zero. |
| 414 Hence, `ismatrix ([])' was false, | |
| 415 while `ismatrix (zeros (1,2,0))' was true. | |
| 9873 | 416 |
| 10118 | 417 * The `issquare' function now returns a logical scalar, and is |
| 418 equivalent to the expression | |
| 419 | |
| 420 ismatrix (x) && ndims (x) == 2 && rows (x) == columns (x) | |
| 421 | |
| 422 The dimension is no longer returned. As a result, `issquare ([])' | |
| 423 now yields true. | |
| 9873 | 424 |
| 10118 | 425 * The `issymmetric' function now checks for symmetry instead of |

426 Hermitianness. For the latter, ishermitian was created. Also, |
| 10118 | 427 logical scalar is returned rather than the dimension, so |
| 428 `issymmetric ([])' is now true. | |
| 9873 | 429 |
| 10118 | 430 ** Function handles are now aware of overloaded functions. If a |
| 431 function is overloaded, the handle determines at the time of its | |
| 432 reference which function to call. A non-overloaded version does not | |
| 433 need to exist. | |
| 9873 | 434 |
| 10118 | 435 ** Overloading functions for built-in classes (double, int8, cell, |
| 436 etc.) is now compatible with Matlab. | |
| 9408 | 437 |
| 10323 | 438 ** Function handles can now be compared with the == and != operators, |
| 439 as well as the `isequal' function. | |
| 440 | |
| 10118 | 441 ** Performance of concatenation (using []) and the functions `cat', |
| 442 `horzcat', and `vertcat' has been improved for multidimensional | |
| 443 arrays. | |
| 10117 | 444 |
| 9547 | 445 ** The operation-assignment operators +=, -=, *= and /= now behave more |
| 10118 | 446 efficiently in certain cases. For instance, if M is a matrix and S a |
| 447 scalar, then the statement | |
| 9547 | 448 |
| 10118 | 449 M += S; |
| 9547 | 450 |
| 10118 | 451 will operate on M's data in-place if it is not shared by another |
| 452 variable, usually increasing both time and memory efficiency. | |
| 9547 | 453 |
| 9558 | 454 Only selected common combinations are affected, namely: |
| 9547 | 455 |
| 456 matrix += matrix | |
| 457 matrix -= matrix | |
| 9558 | 458 matrix .*= matrix |
| 459 matrix ./= matrix | |
| 460 | |
| 9547 | 461 matrix += scalar |
| 462 matrix -= scalar | |
| 463 matrix *= scalar | |
| 464 matrix /= scalar | |
| 9558 | 465 |
| 9552 | 466 logical matrix |= logical matrix |
| 467 logical matrix &= logical matrix | |
| 9547 | 468 |
| 10118 | 469 where matrix and scalar belong to the same class. The left-hand |
| 470 side must be a simple variable reference. | |
| 9888 | 471 |
| 10118 | 472 Moreover, when unary operators occur in expressions, Octave will |
| 473 also try to do the operation in-place if it's argument is a | |

474 temporary expression. |
| 9589 | 475 |
| 10118 | 476 ** The effect of comparison operators (<, >, <=, and >=) applied to |
| 477 complex numbers has changed to be consistent with the strict | |
| 478 ordering defined by the `max', `min', and `sort' functions. More | |
| 479 specifically, complex numbers are compared by lexicographical | |
| 480 comparison of the pairs `[abs(z), arg(z)]'. Previously, only real | |
| 14188 | 481 parts were compared; this can be trivially achieved by converting |
| 482 the operands to real values with the `real' function. | |
| 9547 | 483 |
| 10118 | 484 ** The automatic simplification of complex computation results has |
| 485 changed. Octave will now simplify any complex number with a zero | |
| 486 imaginary part or any complex matrix with all elements having zero | |
| 487 imaginary part to a real value. Previously, this was done only for | |
| 488 positive zeros. Note that the behavior of the complex function is | |
| 489 unchanged and it still produces a complex value even if the | |
| 490 imaginary part is zero. | |
| 9826 | 491 |
| 10118 | 492 ** As a side effect of code refactoring in liboctave, the binary |
| 493 logical operations are now more easily amenable to compiler | |
| 494 optimizations and are thus significantly faster. | |
| 9595 | 495 |
| 10118 | 496 ** Octave now allows user-defined `subsasgn' methods to optimize out |
| 497 redundant copies. For more information, see the manual. | |
| 9595 | 498 |
| 10453 | 499 ** More efficient matrix division handling. Octave is now able to |
| 10118 | 500 handle the expressions |

504 V / M |
| 9664 | 505 |
| 10118 | 506 (M is a matrix and V is a vector) more efficiently in certain cases. |
| 507 In particular, if M is triangular, all three expressions will be | |
| 508 handled by a single call to xTRTRS (from LAPACK), with appropriate | |
| 10453 | 509 flags. Previously, all three expressions required a physical |
| 10118 | 510 transpose of M. |
| 9664 | 511 |
| 10118 | 512 ** More efficient handling of certain mixed real-complex matrix |
| 513 operations. For instance, if RM is a real matrix and CM a complex | |
| 514 matrix, | |
| 9664 | 515 |
| 10118 | 516 RM * CM |
| 9664 | 517 |
| 518 can now be evaluated either as | |
| 519 | |
| 520 complex (RM * real (CM), RM * imag (CM)) | |
| 521 | |
| 522 or as | |
| 523 | |
| 524 complex (RM) * CM, | |
| 525 | |
| 10453 | 526 depending on the dimensions. The first form requires more |
| 527 temporaries and copying, but halves the FLOP count, which normally | |
| 528 brings better performance if RM has enough rows. Previously, the | |
| 529 second form was always used. | |
| 9664 | 530 |
| 11111 | 531 Matrix division is similarly affected. |
| 9664 | 532 |
| 10118 | 533 ** More efficient handling of triangular matrix factors returned from |
| 534 factorizations. The functions for computing QR, LU and Cholesky | |
| 535 factorizations will now automatically return the triangular matrix | |
| 536 factors with proper internal matrix_type set, so that it won't need | |
| 537 to be computed when the matrix is used for division. | |
| 9717 | 538 |
| 10118 | 539 ** The built-in `sum' function now handles the non-native summation |
| 540 (i.e., double precision sum of single or integer inputs) more | |
| 541 efficiently, avoiding a temporary conversion of the whole input | |
| 542 array to doubles. Further, `sum' can now accept an extra option | |
| 543 argument, using a compensated summation algorithm rather than a | |
| 544 straightforward sum, which significantly improves precision if lots | |
| 545 of cancellation occurs in the summation. | |
| 9717 | 546 |
| 10118 | 547 ** The built-in `bsxfun' function now uses optimized code for certain |
| 548 cases where built-in operator handles are passed in. Namely, the | |
| 549 optimizations concern the operators `plus', `minus', `times', | |
| 550 `ldivide', `rdivide', `power', `and', `or' (for logical arrays), | |
| 551 the relational operators `eq', `ne', `lt', `le', `gt', `ge', and the | |
| 552 functions `min' and `max'. Optimizations only apply when both | |
| 553 operands are of the same built-in class. Mixed real/complex and | |
| 554 single/double operations will first convert both operands to a | |
| 555 common type. | |
| 9745 | 556 |
| 10118 | 557 ** The `strfind' and `strrep' functions now have compiled |
| 558 implementations, facilitating significantly more efficient searching | |
| 559 and replacing in strings, especially with longer patterns. The code | |
| 560 of `strcat' has been vectorized and is now much more efficient when | |
| 561 many strings are concatenated. The `strcmpi' and `strncmpi' | |
| 562 functions are now built-in functions, providing better performance. | |

| 10453 | 587 ** rem and mod are now built-in functions. They also handle integer |
| 588 types efficiently using integer arithmetic. | |
| 10437 | 589 |
| 10536 | 590 ** Sparse indexing and indexed assignment has been mostly rewritten. |
| 591 Since Octave uses compressed column storage for sparse matrices, | |
| 592 major attention is devoted to operations manipulating whole columns. | |
| 593 Such operations are now significantly faster, as well as some other | |
| 594 important cases. | |
| 595 | |
| 596 Further, it is now possible to pre-allocate a sparse matrix and | |
| 597 subsequently fill it by assignments, provided they meet certain | |
| 598 conditions. For more information, consult the `spalloc' function, | |
| 599 which is no longer a mere dummy. Consequently, nzmax and nnz are no | |
| 11111 | 600 longer always equal in Octave. Octave may also produce a matrix |
| 601 with nnz < nzmax as a result of other operations, so you should | |

602 consistently use nnz unless you really want to use nzmax (i.e., the |
| 11111 | 603 space allocated for nonzero elements). |
| 10536 | 604 |
| 605 Sparse concatenation is also affected, and concatenating sparse | |
| 606 matrices, especially larger collections, is now significantly more | |
| 11111 | 607 efficient. This applies to both the [] operator and the |
| 10536 | 608 cat/vertcat/horzcat functions. |

| 11111 | 612 of the default xGESVD, using the configuration pseudo-variable |
| 613 svd_driver. The xGESDD driver can be up to 6x times faster when | |
| 614 singular vectors are requested, but is reported to be somewhat less | |
| 10639 | 615 robust on highly ill-conditioned matrices. |
| 616 | |
| 617 ** Configuration pseudo-variables, such as page_screen_output or | |

833 __gnuplot_show__, __gnuplot_replot__, __gnuplot_splot__, |
| 8737 | 834 __gnuplot_save_data__ and __gnuplot_send_inline_data__ have been |
| 835 removed from Octave. These function were incompatible with the | |
| 836 high level graphics handle code. | |
| 6329 | 837 |
| 8885 | 838 ** The Control, Finance and Quaternion functions have been removed. |
| 839 | |
| 840 These functions are now available as separate packages from | |
| 841 | |
| 842 http://octave.sourceforge.net/packages.html | |
| 843 | |
| 844 and can be reinstalled using the Octave package manager (see | |
| 845 the pkg function). | |
| 846 | |
| 847 ** Specific sparse matrix functions removed. | |
| 848 | |
| 849 The following functions, which handled only sparse matrices have | |
| 850 been removed. Instead of calling these functions directly, you | |
| 851 should use the corresponding function without the "sp" prefix. | |
| 8737 | 852 |

| 857 spcumprod spinv spmin | |
| 858 | |
| 859 ** Improvements to the debugger. | |
| 860 | |
| 861 The interactive debugging features have been improved. Stopping | |
| 862 on statements with dbstop should work correctly now. Stepping | |
| 863 into and over functions, and stepping one statement at a time | |
| 864 (with dbstep) now works. Moving up and down the call stack with | |
| 865 dbup and dbdown now works. The dbstack function is now available | |
| 866 to print the current function call stack. The new dbquit function | |
| 867 is available to exit the debugging mode. | |
| 868 | |
| 869 ** Improved traceback error messages. | |
| 870 | |
| 871 Traceback error messages are much more concise and easier to | |
| 872 understand. They now display information about the function call | |
| 873 stack instead of the stack of all statements that were active at | |
| 874 the point of the error. | |

877 |
| 8737 | 878 Octave now includes OOP features and the user can create their own |
| 879 class objects and overloaded functions and operators. For | |
| 880 example, all methods of a class called "myclass" will be found in | |
| 881 a directory "@myclass" on the users path. The class specific | |
| 882 versions of functions and operators take precedence over the | |
| 883 generic versions of these functions. | |
| 884 | |
| 885 New functions related to OOP include | |
| 7189 | 886 |
| 8737 | 887 class inferiorto isobject loadobj methods superiorto |
| 888 | |
| 889 See the Octave manual for more details. | |
| 7038 | 890 |
| 8747 | 891 ** Parsing of Command-style Functions. |
| 892 | |
| 893 Octave now parses command-style functions without needing to first | |
| 894 declare them with "mark_as_command". The rules for recognizing a | |
| 895 command-style function calls are | |
| 896 | |
| 897 * A command must appear as the first word in a statement, | |
| 898 followed by a space. | |
| 899 | |
| 900 * The first character after the space must not be '=' or '(' | |
| 901 | |
| 902 * The next token after the space must not look like a binary | |
| 903 operator. | |
| 904 | |
| 905 These rules should be mostly compatible with the way Matlab parses | |
| 906 command-style function calls and allow users to define commands in | |
| 907 .m files without having to mark them as commands. | |
| 908 | |
| 909 Note that previous versions of Octave allowed expressions like | |
| 910 | |
| 911 x = load -text foo.dat | |
| 912 | |
| 913 but an expression like this will now generate a parse error. In | |
| 914 order to assign the value returned by a function to a variable, | |
| 915 you must use the normal function call syntax: | |
| 916 | |
| 917 x = load ("-text", "foo.dat"); | |
| 918 | |
| 8737 | 919 ** Block comments. |
| 920 | |
| 8747 | 921 Commented code can be between matching "#{" and "#}" or "%{" and |
| 922 "%}" markers, even if the commented code spans several line. This | |
| 923 allows blocks code to be commented, without needing to comment | |
| 924 each line. For example, | |
| 5814 | 925 |
| 8747 | 926 function [s, t] = func (x, y) |
| 927 s = 2 * x; | |
| 928 #{ | |
| 929 s *= y; | |
| 930 t = y + x; | |
| 931 #} | |

1012 subtracting a scalar, and multiplying by a scalar. Ranges with zero |
| 10453 | 1013 increment are allowed and can be constructed using the built-in |
| 1014 function `ones'. | |
| 9006 | 1015 |
| 1016 ** Various performance improvements. | |
| 1017 | |
| 10453 | 1018 Performance of a number of other built-in operations and functions |
| 1019 was improved, including: | |
| 9006 | 1020 |
| 1021 * logical operations | |
| 1022 * comparison operators | |
| 1023 * element-wise power | |
| 1024 * accumarray | |

| 1027 * isinf | |
| 1028 * isfinite | |
| 1029 * nchoosek | |
| 1030 * repmat | |
| 1031 * strcmp | |
| 1032 | |
| 8737 | 1033 ** 64-bit integer arithmetic. |
| 1034 | |
| 1035 Arithmetic with 64-bit integers (int64 and uint64 types) is fully | |
| 1036 supported, with saturation semantics like the other integer types. | |
| 1037 Performance of most integer arithmetic operations has been | |
| 1038 improved by using integer arithmetic directly. Previously, Octave | |
| 1039 performed integer math with saturation semantics by converting the | |
| 1040 operands to double precision, performing the operation, and then | |
| 1041 converting the result back to an integer value, truncating if | |
| 1042 necessary. | |
| 1043 | |
| 8885 | 1044 ** Diagonal and permutation matrices. |
| 1045 | |
| 1046 The interpreter can now treat diagonal and permutation matrices as | |
| 1047 special objects that store only the non-zero elements, rather than | |
| 1048 general full matrices. Therefore, it is now possible to construct | |
| 1049 and use these matrices in linear algebra without suffering a | |
| 1050 performance penalty due to storing large numbers of zero elements. | |
| 1051 | |
| 1052 ** Improvements to fsolve. | |
| 1053 | |
| 1054 The fsolve function now accepts an option structure argument (see | |
| 1055 also the optimset function). The INFO values returned from fsolve | |
| 1056 have changed to be compatible with Matlab's fsolve function. | |
| 1057 Additionally, fsolve is now able to solve overdetermined systems, | |
| 1058 complex-differentiable complex systems, systems with a sparse | |
| 1059 jacobian and can work in single precision if given single precision | |
