651 |
10118 | 652 ** The `lookup' function was extended to be more useful for |
653 general-purpose binary searching. Using this improvement, the | |
654 ismember function was rewritten for significantly better | |
655 performance. | |
9352 | 656 |
657 ** Real, integer and logical matrices, when used in indexing, will now | |
658 cache the internal index_vector value (zero-based indices) when | |
659 successfully used as indices, eliminating the conversion penalty for | |
10118 | 660 subsequent indexing by the same matrix. In particular, this means it |
661 is no longer needed to avoid repeated indexing by logical arrays | |
662 using find for performance reasons. | |
9888 | 663 |
10118 | 664 ** Logical matrices are now treated more efficiently when used as |
665 indices. Octave will keep the index as a logical mask unless the | |
666 ratio of true elements is small enough, using a specialized | |
667 code. Previously, all logical matrices were always first converted | |
668 to index vectors. This results in savings in both memory and | |
669 computing time. | |
9480 | 670 |
10118 | 671 ** The `sub2ind' and `ind2sub' functions were reimplemented as compiled |
672 functions for better performance. These functions are now faster, | |
673 can deliver more economized results for ranges, and can reuse the | |
674 index cache mechanism described in previous paragraph. | |
675 | |
676 ** The built-in function equivalents to associative operators (`plus', | |
677 `times', `mtimes', `and', and `or') have been extended to accept | |
678 multiple arguments. This is especially useful for summing | |
679 (multiplying, etc.) lists of objects (of possibly distinct types): | |
9408 | 680 |
9449 | 681 matrix_sum = plus (matrix_list{:}); |
682 | |
10118 | 683 ** An FTP object type based on libcurl has been implemented. These |
684 objects allow ftp connections, downloads and uploads to be | |
685 managed. For example, | |
9880 | 686 |
10118 | 687 fp = ftp ("ftp.octave.org); |
688 cd (fp, "gnu/octave"); | |
689 mget (fp, "octave-3.2.3.tar.bz2"); | |
690 close (fp); | |
9880 | 691 |
10118 | 692 ** The default behavior of `assert (observed, expected)' has been |
693 relaxed to employ less strict checking that does not require the | |
694 internals of the values to match. This avoids previously valid | |
695 tests from breaking due to new internal classes introduced in future | |
696 Octave versions. | |
9449 | 697 |
698 For instance, all of these assertions were true in Octave 3.0.x | |
699 but false in 3.2.x due to new optimizations and improvements: | |
700 | |
701 assert (2*linspace (1, 5, 5), 2*(1:5)) | |
702 assert (zeros (0, 0), []) | |
703 assert (2*ones (1, 5), (2) (ones (1,5))) | |
9462 | 704 |
10118 | 705 ** The behavior of library functions `ismatrix', `issquare', and |
706 `issymmetric' has been changed for better consistency. | |
9873 | 707 |
10292 | 708 * The `ismatrix' function now returns true for all numeric, |

709 logical and character 2-D or N-D matrices. Previously, `ismatrix' |
10292 | 710 returned false if the first or second dimension was zero. |
711 Hence, `ismatrix ([])' was false, | |
712 while `ismatrix (zeros (1,2,0))' was true. | |
9873 | 713 |
10118 | 714 * The `issquare' function now returns a logical scalar, and is |
715 equivalent to the expression | |
716 | |
717 ismatrix (x) && ndims (x) == 2 && rows (x) == columns (x) | |
718 | |
719 The dimension is no longer returned. As a result, `issquare ([])' | |
720 now yields true. | |
9873 | 721 |
10118 | 722 * The `issymmetric' function now checks for symmetry instead of |

723 Hermitianness. For the latter, ishermitian was created. Also, |
10118 | 724 logical scalar is returned rather than the dimension, so |
725 `issymmetric ([])' is now true. | |
9873 | 726 |
10118 | 727 ** Function handles are now aware of overloaded functions. If a |
728 function is overloaded, the handle determines at the time of its | |
729 reference which function to call. A non-overloaded version does not | |
730 need to exist. | |
9873 | 731 |
10118 | 732 ** Overloading functions for built-in classes (double, int8, cell, |
733 etc.) is now compatible with Matlab. | |
9408 | 734 |
10323 | 735 ** Function handles can now be compared with the == and != operators, |
736 as well as the `isequal' function. | |
737 | |
10118 | 738 ** Performance of concatenation (using []) and the functions `cat', |
739 `horzcat', and `vertcat' has been improved for multidimensional | |
740 arrays. | |
10117 | 741 |
9547 | 742 ** The operation-assignment operators +=, -=, *= and /= now behave more |
10118 | 743 efficiently in certain cases. For instance, if M is a matrix and S a |
744 scalar, then the statement | |
9547 | 745 |
10118 | 746 M += S; |
9547 | 747 |
10118 | 748 will operate on M's data in-place if it is not shared by another |
749 variable, usually increasing both time and memory efficiency. | |
9547 | 750 |
9558 | 751 Only selected common combinations are affected, namely: |
9547 | 752 |
753 matrix += matrix | |
754 matrix -= matrix | |
9558 | 755 matrix .*= matrix |
756 matrix ./= matrix | |
757 | |
9547 | 758 matrix += scalar |
759 matrix -= scalar | |
760 matrix *= scalar | |
761 matrix /= scalar | |
9558 | 762 |
9552 | 763 logical matrix |= logical matrix |
764 logical matrix &= logical matrix | |
9547 | 765 |
10118 | 766 where matrix and scalar belong to the same class. The left-hand |
767 side must be a simple variable reference. | |
9888 | 768 |
10118 | 769 Moreover, when unary operators occur in expressions, Octave will |
770 also try to do the operation in-place if it's argument is a | |

771 temporary expression. |
9589 | 772 |
10118 | 773 ** The effect of comparison operators (<, >, <=, and >=) applied to |
774 complex numbers has changed to be consistent with the strict | |
775 ordering defined by the `max', `min', and `sort' functions. More | |
776 specifically, complex numbers are compared by lexicographical | |
777 comparison of the pairs `[abs(z), arg(z)]'. Previously, only real | |
14188 | 778 parts were compared; this can be trivially achieved by converting |
779 the operands to real values with the `real' function. | |
9547 | 780 |
10118 | 781 ** The automatic simplification of complex computation results has |
782 changed. Octave will now simplify any complex number with a zero | |
783 imaginary part or any complex matrix with all elements having zero | |
784 imaginary part to a real value. Previously, this was done only for | |
785 positive zeros. Note that the behavior of the complex function is | |
786 unchanged and it still produces a complex value even if the | |
787 imaginary part is zero. | |
9826 | 788 |
10118 | 789 ** As a side effect of code refactoring in liboctave, the binary |
790 logical operations are now more easily amenable to compiler | |
791 optimizations and are thus significantly faster. | |
9595 | 792 |
10118 | 793 ** Octave now allows user-defined `subsasgn' methods to optimize out |
794 redundant copies. For more information, see the manual. | |
9595 | 795 |
10453 | 796 ** More efficient matrix division handling. Octave is now able to |
10118 | 797 handle the expressions |

801 V / M |
9664 | 802 |
10118 | 803 (M is a matrix and V is a vector) more efficiently in certain cases. |
804 In particular, if M is triangular, all three expressions will be | |
805 handled by a single call to xTRTRS (from LAPACK), with appropriate | |
10453 | 806 flags. Previously, all three expressions required a physical |
10118 | 807 transpose of M. |
9664 | 808 |
10118 | 809 ** More efficient handling of certain mixed real-complex matrix |
810 operations. For instance, if RM is a real matrix and CM a complex | |
811 matrix, | |
9664 | 812 |
10118 | 813 RM * CM |
9664 | 814 |
815 can now be evaluated either as | |
816 | |
817 complex (RM * real (CM), RM * imag (CM)) | |
818 | |
819 or as | |
820 | |
821 complex (RM) * CM, | |
822 | |
10453 | 823 depending on the dimensions. The first form requires more |
824 temporaries and copying, but halves the FLOP count, which normally | |
825 brings better performance if RM has enough rows. Previously, the | |
826 second form was always used. | |
9664 | 827 |
11111 | 828 Matrix division is similarly affected. |
9664 | 829 |
10118 | 830 ** More efficient handling of triangular matrix factors returned from |
831 factorizations. The functions for computing QR, LU and Cholesky | |
832 factorizations will now automatically return the triangular matrix | |
833 factors with proper internal matrix_type set, so that it won't need | |
834 to be computed when the matrix is used for division. | |
9717 | 835 |
10118 | 836 ** The built-in `sum' function now handles the non-native summation |
837 (i.e., double precision sum of single or integer inputs) more | |
838 efficiently, avoiding a temporary conversion of the whole input | |
839 array to doubles. Further, `sum' can now accept an extra option | |
840 argument, using a compensated summation algorithm rather than a | |
841 straightforward sum, which significantly improves precision if lots | |
842 of cancellation occurs in the summation. | |
9717 | 843 |
10118 | 844 ** The built-in `bsxfun' function now uses optimized code for certain |
845 cases where built-in operator handles are passed in. Namely, the | |
846 optimizations concern the operators `plus', `minus', `times', | |
847 `ldivide', `rdivide', `power', `and', `or' (for logical arrays), | |
848 the relational operators `eq', `ne', `lt', `le', `gt', `ge', and the | |
849 functions `min' and `max'. Optimizations only apply when both | |
850 operands are of the same built-in class. Mixed real/complex and | |
851 single/double operations will first convert both operands to a | |
852 common type. | |
9745 | 853 |
10118 | 854 ** The `strfind' and `strrep' functions now have compiled |
855 implementations, facilitating significantly more efficient searching | |
856 and replacing in strings, especially with longer patterns. The code | |
857 of `strcat' has been vectorized and is now much more efficient when | |
858 many strings are concatenated. The `strcmpi' and `strncmpi' | |
859 functions are now built-in functions, providing better performance. | |

864 has been removed. |
10208 | 865 |
10453 | 866 ** Matlab-style ignoring input and output function arguments using |
11111 | 867 tilde (~) is now supported. Ignored output arguments may be |
868 detected from a function using the built-in function `isargout'. | |
869 For more details, consult the manual. | |
10886 | 870 |
10453 | 871 ** The list datatype, deprecated since the introduction of cells, has |
872 been removed. | |
10276 | 873 |
10453 | 874 ** The accumarray function has been optimized and is now significantly |
875 faster in certain important cases. | |
10054 | 876 |
10292 | 877 ** The behavior of isreal and isnumeric functions was changed to be more |
878 Matlab-compatible. | |

10406 | 880 ** The integer math & conversion warnings (Octave:int-convert-nan, |
881 Octave:int-convert-non-int-val, Octave:int-convert-overflow, | |
11111 | 882 Octave:int-math-overflow) have been removed. |
10406 | 883 |
10453 | 884 ** rem and mod are now built-in functions. They also handle integer |
885 types efficiently using integer arithmetic. | |
10437 | 886 |
10536 | 887 ** Sparse indexing and indexed assignment has been mostly rewritten. |
888 Since Octave uses compressed column storage for sparse matrices, | |
889 major attention is devoted to operations manipulating whole columns. | |
890 Such operations are now significantly faster, as well as some other | |
891 important cases. | |
892 | |
893 Further, it is now possible to pre-allocate a sparse matrix and | |
894 subsequently fill it by assignments, provided they meet certain | |
895 conditions. For more information, consult the `spalloc' function, | |
896 which is no longer a mere dummy. Consequently, nzmax and nnz are no | |
11111 | 897 longer always equal in Octave. Octave may also produce a matrix |
898 with nnz < nzmax as a result of other operations, so you should | |

899 consistently use nnz unless you really want to use nzmax (i.e., the |
11111 | 900 space allocated for nonzero elements). |
10536 | 901 |
902 Sparse concatenation is also affected, and concatenating sparse | |
903 matrices, especially larger collections, is now significantly more | |
11111 | 904 efficient. This applies to both the [] operator and the |
10536 | 905 cat/vertcat/horzcat functions. |
906 | |
11111 | 907 ** It is now possible to optionally employ the xGESDD LAPACK drivers |
14188 | 908 for computing the singular value decomposition using svd, instead |
11111 | 909 of the default xGESVD, using the configuration pseudo-variable |
910 svd_driver. The xGESDD driver can be up to 6x times faster when | |
911 singular vectors are requested, but is reported to be somewhat less | |
10639 | 912 robust on highly ill-conditioned matrices. |
913 | |
914 ** Configuration pseudo-variables, such as page_screen_output or | |
915 confirm_recursive_rmdir (or the above mentioned svd_driver), now | |
916 accept a "local" option as second argument, requesting the change | |

8737 | 1131 __gnuplot_save_data__ and __gnuplot_send_inline_data__ have been |
1132 removed from Octave. These function were incompatible with the | |
1133 high level graphics handle code. | |
6329 | 1134 |
8885 | 1135 ** The Control, Finance and Quaternion functions have been removed. |
1136 | |
1137 These functions are now available as separate packages from | |
1138 | |
1139 http://octave.sourceforge.net/packages.html | |
1140 | |
1141 and can be reinstalled using the Octave package manager (see | |
1142 the pkg function). | |
1143 | |
1144 ** Specific sparse matrix functions removed. | |
1145 | |
1146 The following functions, which handled only sparse matrices have | |
1147 been removed. Instead of calling these functions directly, you | |
1148 should use the corresponding function without the "sp" prefix. | |
8737 | 1149 |

1154 spcumprod spinv spmin | |
1155 | |
1156 ** Improvements to the debugger. | |
1157 | |
1158 The interactive debugging features have been improved. Stopping | |
1159 on statements with dbstop should work correctly now. Stepping | |
1160 into and over functions, and stepping one statement at a time | |
1161 (with dbstep) now works. Moving up and down the call stack with | |
1162 dbup and dbdown now works. The dbstack function is now available | |
1163 to print the current function call stack. The new dbquit function | |
1164 is available to exit the debugging mode. | |
1165 | |
1166 ** Improved traceback error messages. | |
1167 | |
1168 Traceback error messages are much more concise and easier to | |
1169 understand. They now display information about the function call | |
1170 stack instead of the stack of all statements that were active at | |
1171 the point of the error. | |

1174 |
8737 | 1175 Octave now includes OOP features and the user can create their own |
1176 class objects and overloaded functions and operators. For | |
1177 example, all methods of a class called "myclass" will be found in | |
1178 a directory "@myclass" on the users path. The class specific | |
1179 versions of functions and operators take precedence over the | |
1180 generic versions of these functions. | |
1181 | |
1182 New functions related to OOP include | |
7189 | 1183 |
8737 | 1184 class inferiorto isobject loadobj methods superiorto |
1185 | |
1186 See the Octave manual for more details. | |
7038 | 1187 |
8747 | 1188 ** Parsing of Command-style Functions. |
1189 | |
1190 Octave now parses command-style functions without needing to first | |
1191 declare them with "mark_as_command". The rules for recognizing a | |
1192 command-style function calls are | |
1193 | |
1194 * A command must appear as the first word in a statement, | |
1195 followed by a space. | |
1196 | |
1197 * The first character after the space must not be '=' or '(' | |
1198 | |
1199 * The next token after the space must not look like a binary | |
1200 operator. | |
1201 | |
1202 These rules should be mostly compatible with the way Matlab parses | |
1203 command-style function calls and allow users to define commands in | |
1204 .m files without having to mark them as commands. | |
1205 | |
1206 Note that previous versions of Octave allowed expressions like | |
1207 | |
1208 x = load -text foo.dat | |
1209 | |
1210 but an expression like this will now generate a parse error. In | |
1211 order to assign the value returned by a function to a variable, | |
1212 you must use the normal function call syntax: | |
1213 | |
1214 x = load ("-text", "foo.dat"); | |
1215 | |
8737 | 1216 ** Block comments. |
1217 | |
8747 | 1218 Commented code can be between matching "#{" and "#}" or "%{" and |
1219 "%}" markers, even if the commented code spans several line. This | |
1220 allows blocks code to be commented, without needing to comment | |
1221 each line. For example, | |
5814 | 1222 |
8747 | 1223 function [s, t] = func (x, y) |
1224 s = 2 * x; | |
1225 #{ | |
1226 s *= y; | |
1227 t = y + x; | |
1228 #} | |

1284 conversions between cells, structs and cs-lists. This usually reduces |

9128 | 1286 Also, Octave will now attempt to detect and optimize usage of a vector |

8738 | 1290 ** Improved performance for reduction operations. |

1300 efficient algorithm, especially in the homogeneous case. The lookup |
10453 | 1301 function is now a built-in function performing a binary search, |
1302 optimized for long runs of close elements. Lookup also works with | |
1303 cell arrays of strings. | |

1309 subtracting a scalar, and multiplying by a scalar. Ranges with zero |
10453 | 1310 increment are allowed and can be constructed using the built-in |
1311 function `ones'. | |
9006 | 1312 |
1313 ** Various performance improvements. | |
1314 | |
10453 | 1315 Performance of a number of other built-in operations and functions |
1316 was improved, including: | |
9006 | 1317 |
1318 * logical operations | |
1319 * comparison operators | |
1320 * element-wise power | |
1321 * accumarray | |
1322 * cellfun | |
1323 * isnan | |
1324 * isinf | |

1329 | |
8737 | 1330 ** 64-bit integer arithmetic. |
1331 | |
1332 Arithmetic with 64-bit integers (int64 and uint64 types) is fully | |
1333 supported, with saturation semantics like the other integer types. | |
1334 Performance of most integer arithmetic operations has been | |
1335 improved by using integer arithmetic directly. Previously, Octave | |
1336 performed integer math with saturation semantics by converting the | |
1337 operands to double precision, performing the operation, and then | |
1338 converting the result back to an integer value, truncating if | |
1339 necessary. | |
1340 | |
8885 | 1341 ** Diagonal and permutation matrices. |
1342 | |
1343 The interpreter can now treat diagonal and permutation matrices as | |
1344 special objects that store only the non-zero elements, rather than | |
1345 general full matrices. Therefore, it is now possible to construct | |
1346 and use these matrices in linear algebra without suffering a | |
1347 performance penalty due to storing large numbers of zero elements. | |
1348 | |
1349 ** Improvements to fsolve. | |
1350 | |
1351 The fsolve function now accepts an option structure argument (see | |
1352 also the optimset function). The INFO values returned from fsolve | |
1353 have changed to be compatible with Matlab's fsolve function. | |
1354 Additionally, fsolve is now able to solve overdetermined systems, | |
1355 complex-differentiable complex systems, systems with a sparse | |
1356 jacobian and can work in single precision if given single precision | |

1360 | |
1361 The norm function is now able to compute row or column norms of a | |
1362 matrix in a single call, as well as general matrix p-norms. | |
1363 | |
1364 ** New functions for computing some eigenvalues or singular values. | |
1365 | |
1366 The eigs and svds functions have been included in Octave. These | |
1367 functions require the ARPACK library (now distributed under a | |

1412 | |
1413 The strcat function is now compatible with Matlab's strcat | |
1414 function, which removes trailing whitespace when concatenating | |
1415 character strings. For example | |
1416 | |
1417 strcat ('foo ', 'bar') | |
1418 ==> 'foobar' | |

1425 The help system has been mostly re-implemented in .m files to make |
8885 | 1426 it easier to modify. Performance of the lookfor function has been |
1427 greatly improved by caching the help text from all functions that | |
1428 are distributed with Octave. The pkg function has been modified | |
1429 to generate cache files for external packages when they are | |
1430 installed. | |
