544 |
| 10118 | 545 ** The `lookup' function was extended to be more useful for |
| 546 general-purpose binary searching. Using this improvement, the | |
| 547 ismember function was rewritten for significantly better | |
| 548 performance. | |
| 9352 | 549 |
| 550 ** Real, integer and logical matrices, when used in indexing, will now | |
| 551 cache the internal index_vector value (zero-based indices) when | |
| 552 successfully used as indices, eliminating the conversion penalty for | |
| 10118 | 553 subsequent indexing by the same matrix. In particular, this means it |
| 554 is no longer needed to avoid repeated indexing by logical arrays | |
| 555 using find for performance reasons. | |
| 9888 | 556 |
| 10118 | 557 ** Logical matrices are now treated more efficiently when used as |
| 558 indices. Octave will keep the index as a logical mask unless the | |
| 559 ratio of true elements is small enough, using a specialized | |
| 560 code. Previously, all logical matrices were always first converted | |
| 561 to index vectors. This results in savings in both memory and | |
| 562 computing time. | |
| 9480 | 563 |
| 10118 | 564 ** The `sub2ind' and `ind2sub' functions were reimplemented as compiled |
| 565 functions for better performance. These functions are now faster, | |
| 566 can deliver more economized results for ranges, and can reuse the | |
| 567 index cache mechanism described in previous paragraph. | |
| 568 | |
| 569 ** The built-in function equivalents to associative operators (`plus', | |
| 570 `times', `mtimes', `and', and `or') have been extended to accept | |
| 571 multiple arguments. This is especially useful for summing | |
| 572 (multiplying, etc.) lists of objects (of possibly distinct types): | |
| 9408 | 573 |
| 9449 | 574 matrix_sum = plus (matrix_list{:}); |
| 575 | |
| 10118 | 576 ** An FTP object type based on libcurl has been implemented. These |
| 577 objects allow ftp connections, downloads and uploads to be | |
| 578 managed. For example, | |
| 9880 | 579 |
| 10118 | 580 fp = ftp ("ftp.octave.org); |
| 581 cd (fp, "gnu/octave"); | |
| 582 mget (fp, "octave-3.2.3.tar.bz2"); | |
| 583 close (fp); | |
| 9880 | 584 |
| 10118 | 585 ** The default behavior of `assert (observed, expected)' has been |
| 586 relaxed to employ less strict checking that does not require the | |
| 587 internals of the values to match. This avoids previously valid | |
| 588 tests from breaking due to new internal classes introduced in future | |
| 589 Octave versions. | |
| 9449 | 590 |
| 591 For instance, all of these assertions were true in Octave 3.0.x | |
| 592 but false in 3.2.x due to new optimizations and improvements: | |
| 593 | |
| 594 assert (2*linspace (1, 5, 5), 2*(1:5)) | |
| 595 assert (zeros (0, 0), []) | |
| 596 assert (2*ones (1, 5), (2) (ones (1,5))) | |
| 9462 | 597 |
| 10118 | 598 ** The behavior of library functions `ismatrix', `issquare', and |
| 599 `issymmetric' has been changed for better consistency. | |
| 9873 | 600 |
| 10292 | 601 * The `ismatrix' function now returns true for all numeric, |

602 logical and character 2-D or N-D matrices. Previously, `ismatrix' |
| 10292 | 603 returned false if the first or second dimension was zero. |
| 604 Hence, `ismatrix ([])' was false, | |
| 605 while `ismatrix (zeros (1,2,0))' was true. | |
| 9873 | 606 |
| 10118 | 607 * The `issquare' function now returns a logical scalar, and is |
| 608 equivalent to the expression | |
| 609 | |
| 610 ismatrix (x) && ndims (x) == 2 && rows (x) == columns (x) | |
| 611 | |
| 612 The dimension is no longer returned. As a result, `issquare ([])' | |
| 613 now yields true. | |
| 9873 | 614 |
| 10118 | 615 * The `issymmetric' function now checks for symmetry instead of |

616 Hermitianness. For the latter, ishermitian was created. Also, |
| 10118 | 617 logical scalar is returned rather than the dimension, so |
| 618 `issymmetric ([])' is now true. | |
| 9873 | 619 |
| 10118 | 620 ** Function handles are now aware of overloaded functions. If a |
| 621 function is overloaded, the handle determines at the time of its | |
| 622 reference which function to call. A non-overloaded version does not | |
| 623 need to exist. | |
| 9873 | 624 |
| 10118 | 625 ** Overloading functions for built-in classes (double, int8, cell, |
| 626 etc.) is now compatible with Matlab. | |
| 9408 | 627 |
| 10323 | 628 ** Function handles can now be compared with the == and != operators, |
| 629 as well as the `isequal' function. | |
| 630 | |
| 10118 | 631 ** Performance of concatenation (using []) and the functions `cat', |
| 632 `horzcat', and `vertcat' has been improved for multidimensional | |
| 633 arrays. | |
| 10117 | 634 |
| 9547 | 635 ** The operation-assignment operators +=, -=, *= and /= now behave more |
| 10118 | 636 efficiently in certain cases. For instance, if M is a matrix and S a |
| 637 scalar, then the statement | |
| 9547 | 638 |
| 10118 | 639 M += S; |
| 9547 | 640 |
| 10118 | 641 will operate on M's data in-place if it is not shared by another |
| 642 variable, usually increasing both time and memory efficiency. | |
| 9547 | 643 |
| 9558 | 644 Only selected common combinations are affected, namely: |
| 9547 | 645 |
| 646 matrix += matrix | |
| 647 matrix -= matrix | |
| 9558 | 648 matrix .*= matrix |
| 649 matrix ./= matrix | |
| 650 | |
| 9547 | 651 matrix += scalar |
| 652 matrix -= scalar | |
| 653 matrix *= scalar | |
| 654 matrix /= scalar | |
| 9558 | 655 |
| 9552 | 656 logical matrix |= logical matrix |
| 657 logical matrix &= logical matrix | |
| 9547 | 658 |
| 10118 | 659 where matrix and scalar belong to the same class. The left-hand |
| 660 side must be a simple variable reference. | |
| 9888 | 661 |
| 10118 | 662 Moreover, when unary operators occur in expressions, Octave will |
| 663 also try to do the operation in-place if it's argument is a | |

664 temporary expression. |
| 9589 | 665 |
| 10118 | 666 ** The effect of comparison operators (<, >, <=, and >=) applied to |
| 667 complex numbers has changed to be consistent with the strict | |
| 668 ordering defined by the `max', `min', and `sort' functions. More | |
| 669 specifically, complex numbers are compared by lexicographical | |
| 670 comparison of the pairs `[abs(z), arg(z)]'. Previously, only real | |
| 14188 | 671 parts were compared; this can be trivially achieved by converting |
| 672 the operands to real values with the `real' function. | |
| 9547 | 673 |
| 10118 | 674 ** The automatic simplification of complex computation results has |
| 675 changed. Octave will now simplify any complex number with a zero | |
| 676 imaginary part or any complex matrix with all elements having zero | |
| 677 imaginary part to a real value. Previously, this was done only for | |
| 678 positive zeros. Note that the behavior of the complex function is | |
| 679 unchanged and it still produces a complex value even if the | |
| 680 imaginary part is zero. | |
| 9826 | 681 |
| 10118 | 682 ** As a side effect of code refactoring in liboctave, the binary |
| 683 logical operations are now more easily amenable to compiler | |
| 684 optimizations and are thus significantly faster. | |
| 9595 | 685 |
| 10118 | 686 ** Octave now allows user-defined `subsasgn' methods to optimize out |
| 687 redundant copies. For more information, see the manual. | |
| 9595 | 688 |
| 10453 | 689 ** More efficient matrix division handling. Octave is now able to |
| 10118 | 690 handle the expressions |

694 V / M |
| 9664 | 695 |
| 10118 | 696 (M is a matrix and V is a vector) more efficiently in certain cases. |
| 697 In particular, if M is triangular, all three expressions will be | |
| 698 handled by a single call to xTRTRS (from LAPACK), with appropriate | |
| 10453 | 699 flags. Previously, all three expressions required a physical |
| 10118 | 700 transpose of M. |
| 9664 | 701 |
| 10118 | 702 ** More efficient handling of certain mixed real-complex matrix |
| 703 operations. For instance, if RM is a real matrix and CM a complex | |
| 704 matrix, | |
| 9664 | 705 |
| 10118 | 706 RM * CM |
| 9664 | 707 |
| 708 can now be evaluated either as | |
| 709 | |
| 710 complex (RM * real (CM), RM * imag (CM)) | |
| 711 | |
| 712 or as | |
| 713 | |
| 714 complex (RM) * CM, | |
| 715 | |
| 10453 | 716 depending on the dimensions. The first form requires more |
| 717 temporaries and copying, but halves the FLOP count, which normally | |
| 718 brings better performance if RM has enough rows. Previously, the | |
| 719 second form was always used. | |
| 9664 | 720 |
| 11111 | 721 Matrix division is similarly affected. |
| 9664 | 722 |
| 10118 | 723 ** More efficient handling of triangular matrix factors returned from |
| 724 factorizations. The functions for computing QR, LU and Cholesky | |
| 725 factorizations will now automatically return the triangular matrix | |
| 726 factors with proper internal matrix_type set, so that it won't need | |
| 727 to be computed when the matrix is used for division. | |
| 9717 | 728 |
| 10118 | 729 ** The built-in `sum' function now handles the non-native summation |
| 730 (i.e., double precision sum of single or integer inputs) more | |
| 731 efficiently, avoiding a temporary conversion of the whole input | |
| 732 array to doubles. Further, `sum' can now accept an extra option | |
| 733 argument, using a compensated summation algorithm rather than a | |
| 734 straightforward sum, which significantly improves precision if lots | |
| 735 of cancellation occurs in the summation. | |
| 9717 | 736 |
| 10118 | 737 ** The built-in `bsxfun' function now uses optimized code for certain |
| 738 cases where built-in operator handles are passed in. Namely, the | |
| 739 optimizations concern the operators `plus', `minus', `times', | |
| 740 `ldivide', `rdivide', `power', `and', `or' (for logical arrays), | |
| 741 the relational operators `eq', `ne', `lt', `le', `gt', `ge', and the | |
| 742 functions `min' and `max'. Optimizations only apply when both | |
| 743 operands are of the same built-in class. Mixed real/complex and | |
| 744 single/double operations will first convert both operands to a | |
| 745 common type. | |
| 9745 | 746 |
| 10118 | 747 ** The `strfind' and `strrep' functions now have compiled |
| 748 implementations, facilitating significantly more efficient searching | |
| 749 and replacing in strings, especially with longer patterns. The code | |
| 750 of `strcat' has been vectorized and is now much more efficient when | |
| 751 many strings are concatenated. The `strcmpi' and `strncmpi' | |
| 752 functions are now built-in functions, providing better performance. | |

757 has been removed. |
| 10208 | 758 |
| 10453 | 759 ** Matlab-style ignoring input and output function arguments using |
| 11111 | 760 tilde (~) is now supported. Ignored output arguments may be |
| 761 detected from a function using the built-in function `isargout'. | |
| 762 For more details, consult the manual. | |
| 10886 | 763 |
| 10453 | 764 ** The list datatype, deprecated since the introduction of cells, has |
| 765 been removed. | |
| 10276 | 766 |
| 10453 | 767 ** The accumarray function has been optimized and is now significantly |
| 768 faster in certain important cases. | |
| 10054 | 769 |
| 10292 | 770 ** The behavior of isreal and isnumeric functions was changed to be more |
| 771 Matlab-compatible. | |
| 772 | |
| 10406 | 773 ** The integer math & conversion warnings (Octave:int-convert-nan, |
| 774 Octave:int-convert-non-int-val, Octave:int-convert-overflow, | |
| 11111 | 775 Octave:int-math-overflow) have been removed. |
| 10406 | 776 |
| 10453 | 777 ** rem and mod are now built-in functions. They also handle integer |
| 778 types efficiently using integer arithmetic. | |
| 10437 | 779 |
| 10536 | 780 ** Sparse indexing and indexed assignment has been mostly rewritten. |
| 781 Since Octave uses compressed column storage for sparse matrices, | |
| 782 major attention is devoted to operations manipulating whole columns. | |
| 783 Such operations are now significantly faster, as well as some other | |
| 784 important cases. | |
| 785 | |
| 786 Further, it is now possible to pre-allocate a sparse matrix and | |
| 787 subsequently fill it by assignments, provided they meet certain | |
| 788 conditions. For more information, consult the `spalloc' function, | |
| 789 which is no longer a mere dummy. Consequently, nzmax and nnz are no | |
| 11111 | 790 longer always equal in Octave. Octave may also produce a matrix |
| 791 with nnz < nzmax as a result of other operations, so you should | |

792 consistently use nnz unless you really want to use nzmax (i.e., the |
| 11111 | 793 space allocated for nonzero elements). |
| 10536 | 794 |
| 795 Sparse concatenation is also affected, and concatenating sparse | |
| 796 matrices, especially larger collections, is now significantly more | |
| 11111 | 797 efficient. This applies to both the [] operator and the |
| 10536 | 798 cat/vertcat/horzcat functions. |
| 799 | |
| 11111 | 800 ** It is now possible to optionally employ the xGESDD LAPACK drivers |
| 14188 | 801 for computing the singular value decomposition using svd, instead |
| 11111 | 802 of the default xGESVD, using the configuration pseudo-variable |
| 803 svd_driver. The xGESDD driver can be up to 6x times faster when | |
| 804 singular vectors are requested, but is reported to be somewhat less | |
| 10639 | 805 robust on highly ill-conditioned matrices. |
| 806 | |
| 807 ** Configuration pseudo-variables, such as page_screen_output or | |
| 808 confirm_recursive_rmdir (or the above mentioned svd_driver), now | |
| 809 accept a "local" option as second argument, requesting the change | |

| 8737 | 1024 __gnuplot_save_data__ and __gnuplot_send_inline_data__ have been |
| 1025 removed from Octave. These function were incompatible with the | |
| 1026 high level graphics handle code. | |
| 6329 | 1027 |
| 8885 | 1028 ** The Control, Finance and Quaternion functions have been removed. |
| 1029 | |
| 1030 These functions are now available as separate packages from | |
| 1031 | |
| 1032 http://octave.sourceforge.net/packages.html | |
| 1033 | |
| 1034 and can be reinstalled using the Octave package manager (see | |
| 1035 the pkg function). | |
| 1036 | |
| 1037 ** Specific sparse matrix functions removed. | |
| 1038 | |
| 1039 The following functions, which handled only sparse matrices have | |
| 1040 been removed. Instead of calling these functions directly, you | |
| 1041 should use the corresponding function without the "sp" prefix. | |

| 1048 | |
| 1049 ** Improvements to the debugger. | |
| 1050 | |
| 1051 The interactive debugging features have been improved. Stopping | |
| 1052 on statements with dbstop should work correctly now. Stepping | |
| 1053 into and over functions, and stepping one statement at a time | |
| 1054 (with dbstep) now works. Moving up and down the call stack with | |
| 1055 dbup and dbdown now works. The dbstack function is now available | |
| 1056 to print the current function call stack. The new dbquit function | |
| 1057 is available to exit the debugging mode. | |
| 1058 | |
| 1059 ** Improved traceback error messages. | |
| 1060 | |
| 1061 Traceback error messages are much more concise and easier to | |
| 1062 understand. They now display information about the function call | |
| 1063 stack instead of the stack of all statements that were active at | |
| 1064 the point of the error. | |

1067 |
| 8737 | 1068 Octave now includes OOP features and the user can create their own |
| 1069 class objects and overloaded functions and operators. For | |
| 1070 example, all methods of a class called "myclass" will be found in | |
| 1071 a directory "@myclass" on the users path. The class specific | |
| 1072 versions of functions and operators take precedence over the | |
| 1073 generic versions of these functions. | |
| 1074 | |
| 1075 New functions related to OOP include | |
| 7189 | 1076 |
| 8737 | 1077 class inferiorto isobject loadobj methods superiorto |
| 1078 | |
| 1079 See the Octave manual for more details. | |
| 7038 | 1080 |
| 8747 | 1081 ** Parsing of Command-style Functions. |
| 1082 | |
| 1083 Octave now parses command-style functions without needing to first | |
| 1084 declare them with "mark_as_command". The rules for recognizing a | |
| 1085 command-style function calls are | |
| 1086 | |
| 1087 * A command must appear as the first word in a statement, | |
| 1088 followed by a space. | |
| 1089 | |
| 1090 * The first character after the space must not be '=' or '(' | |
| 1091 | |
| 1092 * The next token after the space must not look like a binary | |
| 1093 operator. | |
| 1094 | |
| 1095 These rules should be mostly compatible with the way Matlab parses | |
| 1096 command-style function calls and allow users to define commands in | |
| 1097 .m files without having to mark them as commands. | |
| 1098 | |
| 1099 Note that previous versions of Octave allowed expressions like | |
| 1100 | |
| 1101 x = load -text foo.dat | |
| 1102 | |
| 1103 but an expression like this will now generate a parse error. In | |
| 1104 order to assign the value returned by a function to a variable, | |
| 1105 you must use the normal function call syntax: | |
| 1106 | |
| 1107 x = load ("-text", "foo.dat"); | |
| 1108 | |
| 8737 | 1109 ** Block comments. |
| 1110 | |
| 8747 | 1111 Commented code can be between matching "#{" and "#}" or "%{" and |
| 1112 "%}" markers, even if the commented code spans several line. This | |
| 1113 allows blocks code to be commented, without needing to comment | |
| 1114 each line. For example, | |
| 5814 | 1115 |
| 8747 | 1116 function [s, t] = func (x, y) |
| 1117 s = 2 * x; | |
| 1118 #{ | |
| 1119 s *= y; | |
| 1120 t = y + x; | |
| 1121 #} | |

1177 conversions between cells, structs and cs-lists. This usually reduces |
| 8755 | 1178 both time and memory consumption. |

1202 subtracting a scalar, and multiplying by a scalar. Ranges with zero |
| 10453 | 1203 increment are allowed and can be constructed using the built-in |
| 1204 function `ones'. | |
| 9006 | 1205 |
| 1206 ** Various performance improvements. | |
| 1207 | |
| 10453 | 1208 Performance of a number of other built-in operations and functions |
| 1209 was improved, including: | |
| 9006 | 1210 |
| 1211 * logical operations | |
| 1212 * comparison operators | |
| 1213 * element-wise power | |
| 1214 * accumarray | |
| 1215 * cellfun | |
| 1216 * isnan | |
| 1217 * isinf | |
| 1218 * isfinite | |
| 1219 * nchoosek | |
| 1220 * repmat | |
| 1221 * strcmp | |
| 1222 | |
| 8737 | 1223 ** 64-bit integer arithmetic. |
| 1224 | |
| 1225 Arithmetic with 64-bit integers (int64 and uint64 types) is fully | |
| 1226 supported, with saturation semantics like the other integer types. | |
| 1227 Performance of most integer arithmetic operations has been | |
| 1228 improved by using integer arithmetic directly. Previously, Octave | |
| 1229 performed integer math with saturation semantics by converting the | |
| 1230 operands to double precision, performing the operation, and then | |
| 1231 converting the result back to an integer value, truncating if | |
| 1232 necessary. | |
| 1233 | |
| 8885 | 1234 ** Diagonal and permutation matrices. |
| 1235 | |
| 1236 The interpreter can now treat diagonal and permutation matrices as | |
| 1237 special objects that store only the non-zero elements, rather than | |
| 1238 general full matrices. Therefore, it is now possible to construct | |
| 1239 and use these matrices in linear algebra without suffering a | |
| 1240 performance penalty due to storing large numbers of zero elements. | |
| 1241 | |
| 1242 ** Improvements to fsolve. | |
| 1243 | |
| 1244 The fsolve function now accepts an option structure argument (see | |
| 1245 also the optimset function). The INFO values returned from fsolve | |
| 1246 have changed to be compatible with Matlab's fsolve function. | |
| 1247 Additionally, fsolve is now able to solve overdetermined systems, | |
| 1248 complex-differentiable complex systems, systems with a sparse | |
| 1249 jacobian and can work in single precision if given single precision | |

| 1255 matrix in a single call, as well as general matrix p-norms. | |
| 1256 | |
| 1257 ** New functions for computing some eigenvalues or singular values. | |
| 1258 | |
| 1259 The eigs and svds functions have been included in Octave. These | |
