10118 | 517 ** The `lookup' function was extended to be more useful for |
518 general-purpose binary searching. Using this improvement, the | |
519 ismember function was rewritten for significantly better | |
520 performance. | |
9352 | 521 |
522 ** Real, integer and logical matrices, when used in indexing, will now | |
523 cache the internal index_vector value (zero-based indices) when | |
524 successfully used as indices, eliminating the conversion penalty for | |
10118 | 525 subsequent indexing by the same matrix. In particular, this means it |
526 is no longer needed to avoid repeated indexing by logical arrays | |
527 using find for performance reasons. | |
9888 | 528 |
10118 | 529 ** Logical matrices are now treated more efficiently when used as |
530 indices. Octave will keep the index as a logical mask unless the | |
531 ratio of true elements is small enough, using a specialized | |
532 code. Previously, all logical matrices were always first converted | |
533 to index vectors. This results in savings in both memory and | |
534 computing time. | |
9480 | 535 |
10118 | 536 ** The `sub2ind' and `ind2sub' functions were reimplemented as compiled |
537 functions for better performance. These functions are now faster, | |
538 can deliver more economized results for ranges, and can reuse the | |
539 index cache mechanism described in previous paragraph. | |
540 | |
541 ** The built-in function equivalents to associative operators (`plus', | |
542 `times', `mtimes', `and', and `or') have been extended to accept | |
543 multiple arguments. This is especially useful for summing | |
544 (multiplying, etc.) lists of objects (of possibly distinct types): | |
9408 | 545 |
9449 | 546 matrix_sum = plus (matrix_list{:}); |
547 | |
10118 | 548 ** An FTP object type based on libcurl has been implemented. These |
549 objects allow ftp connections, downloads and uploads to be | |
550 managed. For example, | |
9880 | 551 |
10118 | 552 fp = ftp ("ftp.octave.org); |
553 cd (fp, "gnu/octave"); | |
554 mget (fp, "octave-3.2.3.tar.bz2"); | |
555 close (fp); | |
9880 | 556 |
10118 | 557 ** The default behavior of `assert (observed, expected)' has been |
558 relaxed to employ less strict checking that does not require the | |
559 internals of the values to match. This avoids previously valid | |
560 tests from breaking due to new internal classes introduced in future | |
561 Octave versions. | |
9449 | 562 |
563 For instance, all of these assertions were true in Octave 3.0.x | |
564 but false in 3.2.x due to new optimizations and improvements: | |
565 | |
566 assert (2*linspace (1, 5, 5), 2*(1:5)) | |
567 assert (zeros (0, 0), []) | |
568 assert (2*ones (1, 5), (2) (ones (1,5))) | |
9462 | 569 |
10118 | 570 ** The behavior of library functions `ismatrix', `issquare', and |
571 `issymmetric' has been changed for better consistency. | |
9873 | 572 |
10292 | 573 * The `ismatrix' function now returns true for all numeric, |

574 logical and character 2-D or N-D matrices. Previously, `ismatrix' |
10292 | 575 returned false if the first or second dimension was zero. |
576 Hence, `ismatrix ([])' was false, | |
577 while `ismatrix (zeros (1,2,0))' was true. | |
9873 | 578 |
10118 | 579 * The `issquare' function now returns a logical scalar, and is |

588 Hermitianness. For the latter, ishermitian was created. Also, |
10118 | 589 logical scalar is returned rather than the dimension, so |
590 `issymmetric ([])' is now true. | |
9873 | 591 |
10118 | 592 ** Function handles are now aware of overloaded functions. If a |
593 function is overloaded, the handle determines at the time of its | |
594 reference which function to call. A non-overloaded version does not | |
595 need to exist. | |
9873 | 596 |
10118 | 597 ** Overloading functions for built-in classes (double, int8, cell, |
598 etc.) is now compatible with Matlab. | |
9408 | 599 |
10323 | 600 ** Function handles can now be compared with the == and != operators, |
601 as well as the `isequal' function. | |
602 | |
10118 | 603 ** Performance of concatenation (using []) and the functions `cat', |
604 `horzcat', and `vertcat' has been improved for multidimensional | |
605 arrays. | |
10117 | 606 |
9547 | 607 ** The operation-assignment operators +=, -=, *= and /= now behave more |
10118 | 608 efficiently in certain cases. For instance, if M is a matrix and S a |
609 scalar, then the statement | |
9547 | 610 |
10118 | 611 M += S; |
9547 | 612 |
10118 | 613 will operate on M's data in-place if it is not shared by another |
614 variable, usually increasing both time and memory efficiency. | |
9547 | 615 |
9558 | 616 Only selected common combinations are affected, namely: |
9547 | 617 |
618 matrix += matrix | |
619 matrix -= matrix | |
9558 | 620 matrix .*= matrix |
621 matrix ./= matrix | |
622 | |
9547 | 623 matrix += scalar |
624 matrix -= scalar | |
625 matrix *= scalar | |
626 matrix /= scalar | |
9558 | 627 |
9552 | 628 logical matrix |= logical matrix |
629 logical matrix &= logical matrix | |
9547 | 630 |
10118 | 631 where matrix and scalar belong to the same class. The left-hand |
632 side must be a simple variable reference. | |
9888 | 633 |
10118 | 634 Moreover, when unary operators occur in expressions, Octave will |
635 also try to do the operation in-place if it's argument is a | |

636 temporary expression. |
9589 | 637 |
10118 | 638 ** The effect of comparison operators (<, >, <=, and >=) applied to |
639 complex numbers has changed to be consistent with the strict | |
640 ordering defined by the `max', `min', and `sort' functions. More | |
641 specifically, complex numbers are compared by lexicographical | |
642 comparison of the pairs `[abs(z), arg(z)]'. Previously, only real | |
14188 | 643 parts were compared; this can be trivially achieved by converting |
644 the operands to real values with the `real' function. | |
9547 | 645 |
10118 | 646 ** The automatic simplification of complex computation results has |
647 changed. Octave will now simplify any complex number with a zero | |
648 imaginary part or any complex matrix with all elements having zero | |
649 imaginary part to a real value. Previously, this was done only for | |
650 positive zeros. Note that the behavior of the complex function is | |
651 unchanged and it still produces a complex value even if the | |
652 imaginary part is zero. | |
9826 | 653 |
10118 | 654 ** As a side effect of code refactoring in liboctave, the binary |
655 logical operations are now more easily amenable to compiler | |
656 optimizations and are thus significantly faster. | |
9595 | 657 |
10118 | 658 ** Octave now allows user-defined `subsasgn' methods to optimize out |
659 redundant copies. For more information, see the manual. | |
9595 | 660 |
10453 | 661 ** More efficient matrix division handling. Octave is now able to |
10118 | 662 handle the expressions |

666 V / M |
9664 | 667 |
10118 | 668 (M is a matrix and V is a vector) more efficiently in certain cases. |
669 In particular, if M is triangular, all three expressions will be | |
670 handled by a single call to xTRTRS (from LAPACK), with appropriate | |
10453 | 671 flags. Previously, all three expressions required a physical |
10118 | 672 transpose of M. |
9664 | 673 |
10118 | 674 ** More efficient handling of certain mixed real-complex matrix |
675 operations. For instance, if RM is a real matrix and CM a complex | |
676 matrix, | |
9664 | 677 |
10118 | 678 RM * CM |
9664 | 679 |
680 can now be evaluated either as | |
681 | |
682 complex (RM * real (CM), RM * imag (CM)) | |
683 | |
684 or as | |
685 | |
686 complex (RM) * CM, | |
687 | |
10453 | 688 depending on the dimensions. The first form requires more |
689 temporaries and copying, but halves the FLOP count, which normally | |
690 brings better performance if RM has enough rows. Previously, the | |
691 second form was always used. | |
9664 | 692 |
11111 | 693 Matrix division is similarly affected. |
9664 | 694 |
10118 | 695 ** More efficient handling of triangular matrix factors returned from |
696 factorizations. The functions for computing QR, LU and Cholesky | |
697 factorizations will now automatically return the triangular matrix | |
698 factors with proper internal matrix_type set, so that it won't need | |
699 to be computed when the matrix is used for division. | |
9717 | 700 |
10118 | 701 ** The built-in `sum' function now handles the non-native summation |
702 (i.e., double precision sum of single or integer inputs) more | |
703 efficiently, avoiding a temporary conversion of the whole input | |
704 array to doubles. Further, `sum' can now accept an extra option | |
705 argument, using a compensated summation algorithm rather than a | |
706 straightforward sum, which significantly improves precision if lots | |
707 of cancellation occurs in the summation. | |
9717 | 708 |
10118 | 709 ** The built-in `bsxfun' function now uses optimized code for certain |
710 cases where built-in operator handles are passed in. Namely, the | |
711 optimizations concern the operators `plus', `minus', `times', | |
712 `ldivide', `rdivide', `power', `and', `or' (for logical arrays), | |
713 the relational operators `eq', `ne', `lt', `le', `gt', `ge', and the | |
714 functions `min' and `max'. Optimizations only apply when both | |
715 operands are of the same built-in class. Mixed real/complex and | |
716 single/double operations will first convert both operands to a | |
717 common type. | |
9745 | 718 |
10118 | 719 ** The `strfind' and `strrep' functions now have compiled |
720 implementations, facilitating significantly more efficient searching | |
721 and replacing in strings, especially with longer patterns. The code | |
722 of `strcat' has been vectorized and is now much more efficient when | |
723 many strings are concatenated. The `strcmpi' and `strncmpi' | |
724 functions are now built-in functions, providing better performance. | |

733 detected from a function using the built-in function `isargout'. | |
734 For more details, consult the manual. | |
10886 | 735 |
10453 | 736 ** The list datatype, deprecated since the introduction of cells, has |

746 Octave:int-convert-non-int-val, Octave:int-convert-overflow, | |
11111 | 747 Octave:int-math-overflow) have been removed. |
10406 | 748 |
10453 | 749 ** rem and mod are now built-in functions. They also handle integer |
750 types efficiently using integer arithmetic. | |
10437 | 751 |
10536 | 752 ** Sparse indexing and indexed assignment has been mostly rewritten. |
753 Since Octave uses compressed column storage for sparse matrices, | |
754 major attention is devoted to operations manipulating whole columns. | |
755 Such operations are now significantly faster, as well as some other | |
756 important cases. | |
757 | |
758 Further, it is now possible to pre-allocate a sparse matrix and | |
759 subsequently fill it by assignments, provided they meet certain | |
760 conditions. For more information, consult the `spalloc' function, | |
761 which is no longer a mere dummy. Consequently, nzmax and nnz are no | |
11111 | 762 longer always equal in Octave. Octave may also produce a matrix |
763 with nnz < nzmax as a result of other operations, so you should | |

764 consistently use nnz unless you really want to use nzmax (i.e., the |
11111 | 765 space allocated for nonzero elements). |
10536 | 766 |
767 Sparse concatenation is also affected, and concatenating sparse | |
768 matrices, especially larger collections, is now significantly more | |
11111 | 769 efficient. This applies to both the [] operator and the |
10536 | 770 cat/vertcat/horzcat functions. |
771 | |
11111 | 772 ** It is now possible to optionally employ the xGESDD LAPACK drivers |
14188 | 773 for computing the singular value decomposition using svd, instead |
11111 | 774 of the default xGESVD, using the configuration pseudo-variable |
775 svd_driver. The xGESDD driver can be up to 6x times faster when | |
776 singular vectors are requested, but is reported to be somewhat less | |
10639 | 777 robust on highly ill-conditioned matrices. |
778 | |
779 ** Configuration pseudo-variables, such as page_screen_output or | |
780 confirm_recursive_rmdir (or the above mentioned svd_driver), now | |
781 accept a "local" option as second argument, requesting the change | |

1023 The interactive debugging features have been improved. Stopping | |
1024 on statements with dbstop should work correctly now. Stepping | |
1025 into and over functions, and stepping one statement at a time | |
1026 (with dbstep) now works. Moving up and down the call stack with | |
1027 dbup and dbdown now works. The dbstack function is now available | |
1028 to print the current function call stack. The new dbquit function | |
1029 is available to exit the debugging mode. | |
1030 | |
1031 ** Improved traceback error messages. | |
1032 | |
1033 Traceback error messages are much more concise and easier to | |
1034 understand. They now display information about the function call | |
1035 stack instead of the stack of all statements that were active at | |
1036 the point of the error. | |

8737 | 1040 Octave now includes OOP features and the user can create their own |
1041 class objects and overloaded functions and operators. For | |
1042 example, all methods of a class called "myclass" will be found in | |
1043 a directory "@myclass" on the users path. The class specific | |
1044 versions of functions and operators take precedence over the | |
1045 generic versions of these functions. | |
1046 | |
1047 New functions related to OOP include | |
7189 | 1048 |
8737 | 1049 class inferiorto isobject loadobj methods superiorto |
1050 | |
1051 See the Octave manual for more details. | |
7038 | 1052 |
8747 | 1053 ** Parsing of Command-style Functions. |
1054 | |
1055 Octave now parses command-style functions without needing to first | |
1056 declare them with "mark_as_command". The rules for recognizing a | |
1057 command-style function calls are | |
1058 | |
1059 * A command must appear as the first word in a statement, | |
1060 followed by a space. | |
1061 | |
1062 * The first character after the space must not be '=' or '(' | |
1063 | |
1064 * The next token after the space must not look like a binary | |
1065 operator. | |
1066 | |
1067 These rules should be mostly compatible with the way Matlab parses | |
1068 command-style function calls and allow users to define commands in | |
1069 .m files without having to mark them as commands. | |
1070 | |
1071 Note that previous versions of Octave allowed expressions like | |
1072 | |
1073 x = load -text foo.dat | |
1074 | |
1075 but an expression like this will now generate a parse error. In | |
1076 order to assign the value returned by a function to a variable, | |
1077 you must use the normal function call syntax: | |
1078 | |
1079 x = load ("-text", "foo.dat"); | |
1080 | |
8737 | 1081 ** Block comments. |
1082 | |
8747 | 1083 Commented code can be between matching "#{" and "#}" or "%{" and |
1084 "%}" markers, even if the commented code spans several line. This | |
1085 allows blocks code to be commented, without needing to comment | |
1086 each line. For example, | |
5814 | 1087 |
8747 | 1088 function [s, t] = func (x, y) |
1089 s = 2 * x; | |
1090 #{ | |
1091 s *= y; | |
1092 t = y + x; | |
1093 #} | |

1149 conversions between cells, structs and cs-lists. This usually reduces |
8755 | 1150 both time and memory consumption. |
9128 | 1151 Also, Octave will now attempt to detect and optimize usage of a vector |
1152 as a stack, when elements are being repeatedly inserted at/removed from | |
1153 the end of the vector. | |
8755 | 1154 |
8738 | 1155 ** Improved performance for reduction operations. |
1156 | |
8755 | 1157 The performance of the sum, prod, sumsq, cumsum, cumprod, any, all, |

1164 implementation was added. The sortrows function now uses a more | |

1174 subtracting a scalar, and multiplying by a scalar. Ranges with zero |
10453 | 1175 increment are allowed and can be constructed using the built-in |
1176 function `ones'. | |
9006 | 1177 |
1178 ** Various performance improvements. | |
1179 | |
10453 | 1180 Performance of a number of other built-in operations and functions |
1181 was improved, including: | |
9006 | 1182 |
1183 * logical operations | |
1184 * comparison operators | |
1185 * element-wise power | |
1186 * accumarray | |

1189 * isinf | |

1192 * repmat | |
1193 * strcmp | |
1194 | |
8737 | 1195 ** 64-bit integer arithmetic. |
1196 | |
1197 Arithmetic with 64-bit integers (int64 and uint64 types) is fully | |
1198 supported, with saturation semantics like the other integer types. | |
1199 Performance of most integer arithmetic operations has been | |
1200 improved by using integer arithmetic directly. Previously, Octave | |
1201 performed integer math with saturation semantics by converting the | |
1202 operands to double precision, performing the operation, and then | |
1203 converting the result back to an integer value, truncating if | |
1204 necessary. | |
1205 | |
8885 | 1206 ** Diagonal and permutation matrices. |
1207 | |
1208 The interpreter can now treat diagonal and permutation matrices as | |
1209 special objects that store only the non-zero elements, rather than | |
1210 general full matrices. Therefore, it is now possible to construct | |
1211 and use these matrices in linear algebra without suffering a | |
1212 performance penalty due to storing large numbers of zero elements. | |
1213 | |
1214 ** Improvements to fsolve. | |
1215 | |
1216 The fsolve function now accepts an option structure argument (see | |
1217 also the optimset function). The INFO values returned from fsolve | |
1218 have changed to be compatible with Matlab's fsolve function. | |
1219 Additionally, fsolve is now able to solve overdetermined systems, | |
1220 complex-differentiable complex systems, systems with a sparse | |
1221 jacobian and can work in single precision if given single precision | |

1290 The help system has been mostly re-implemented in .m files to make |
8885 | 1291 it easier to modify. Performance of the lookfor function has been |
1292 greatly improved by caching the help text from all functions that | |
1293 are distributed with Octave. The pkg function has been modified | |
1294 to generate cache files for external packages when they are | |
1295 installed. | |
