MATLAB functions renamed colamd2 and symamd2, + so that they do not conflict with the built-in versions. Note that + the MATLAB built-in functions colamd and symamd are identical to + the colamd and symamd functions here. + +Aug 31, 2006: Version 2.5.1 + + * minor change to colamd.m and symamd.m, to use etree instead + of sparsfun. + +Apr. 30, 2006: Version 2.5 + + * colamd_recommended modified, to do more careful integer overflow + checking. It now returns size_t, not int. colamd_l_recommended + also returns size_t. A zero is returned if an error occurs. A + postive return value denotes success. In v2.4 and earlier, + -1 was returned on error (an int or long). + + * long replaced with UF_long integer, which is long except on WIN64. + +Nov 15, 2005: + + * minor editting of comments; version number (2.4) unchanged. + +Changes from Version 2.3 to 2.4 (Aug 30, 2005) + + * Makefile now relies on ../UFconfig/UFconfig.mk + + * changed the dense row/col detection. The meaning of the knobs + has thus changed. + + * added an option to turn off aggressive absorption. It was + always on in versions 2.3 and earlier. + + * added a #define'd version number + + * added a function pointer (colamd_printf) for COLAMD's printing. + + * added a -DNPRINT option, to turn off printing at compile-time. + + * added a check for integer overflow in colamd_recommended + + * minor changes to allow for more simpler 100% test coverage + + * bug fix. If symamd v2.3 fails to allocate its copy of the input + matrix, then it erroneously frees a calloc'd workspace twice. + This bug has no effect on the MATLAB symamd mexFunction, since + mxCalloc terminates the mexFunction if it fails to allocate + memory. Similarly, UMFPACK is not affected because it does not + use symamd. The bug has no effect on the colamd ordering + routine in v2.3. + +Changes from Version 2.2 to 2.3 (Sept. 8, 2003) + + * removed the call to the MATLAB spparms ('spumoni') function. + This can take a lot of time if you are ordering many small + matrices. Only affects the MATLAB interface (colamdmex.c, + symamdmex.c, colamdtestmex.c, and symamdtestmex.c). The + usage of the optional 2nd argument to the colamd and symamd + mexFunctions was changed accordingly. + +Changes from Version 2.1 to 2.2 (Sept. 23, 2002) + + * extensive testing routines added (colamd_test.m, colamdtestmex.c, + and symamdtestmex.c), and the Makefile modified accordingly. + + * a few typos in the comments corrected + + * use of the MATLAB "flops" command removed from colamd_demo, and an + m-file routine luflops.m added. + + * an explicit typecast from unsigned to int added, for COLAMD_C and + COLAMD_R in colamd.h. + + * #include <stdio.h> added to colamd_example.c + + +Changes from Version 2.0 to 2.1 (May 4, 2001) + + * TRUE and FALSE are predefined on some systems, so they are defined + here only if not already defined. + + * web site changed + + * UNIX Makefile modified, to handle the case if "." is not in your path. + + +Changes from Version 1.0 to 2.0 (January 31, 2000) + + No bugs were found in version 1.1. These changes merely add new + functionality. + + * added the COLAMD_RECOMMENDED (nnz, n_row, n_col) macro. + + * moved the output statistics, from A, to a separate output argument. + The arguments changed for the C-callable routines. + + * added colamd_report and symamd_report. + + * added a C-callable symamd routine. Formerly, symamd was only + available as a mexFunction from MATLAB. + + * added error-checking to symamd. Formerly, it assumed its input + was error-free. + + * added the optional stats and knobs arguments to the symamd mexFunction + + * deleted colamd_help. A help message is still available from + "help colamd" and "help symamd" in MATLAB. + + * deleted colamdtree.m and symamdtree.m. Now, colamd.m and symamd.m + also do the elimination tree post-ordering. The Version 1.1 + colamd and symamd mexFunctions, which do not do the post- + ordering, are now visible as colamdmex and symamdmex from + MATLAB. Essentialy, the post-ordering is now the default + behavior of colamd.m and symamd.m, to match the behavior of + colmmd and symmmd. The post-ordering is only available in the + MATLAB interface, not the C-callable interface. + + * made a slight change to the dense row/column detection in symamd, + to match the stated specifications. |
