Jan. 21, 2004: AMD Version 1.1 * No bugs found or fixed - new features added, only * amd_preprocess added, to allow for more general input of the matrix A. * ME=0 added to amd*.f, unused DEXT variable removed from amdbar.f, to avoid spurious compiler warnings (this was not a bug). * amd_demo2.c and amd_demo2.out added, to test/demo amd_preprocess. * option to allow compile-time redefinition of malloc, free, printf added * amd_demo.c shortened slightly (removed printing of PAP') * User Guide modified (more details added) * linewidth reduced from 80 to 79 columns Oct. 7, 2003: AMD version 1.0.1. * MATLAB mexFunction modified, to remove call to mexCallMATLAB function. This function can take a long time to call, particularly if you are ordering many small matrices. May 6, 2003: AMD Version 1.0 released. * converted to C (compare amd.f and amdbar.f with amd_2.c) * dense rows/column removed prior to ordering * elimination tree post-ordering added * demos, user guide written * statistics added (nz in L, flop count, symmetry of A) * computes the pattern of A+A' if A is unsymmetric * user's input matrix no longer overwritten * degree lists initialized differently * IOVFLO argument removed from Fortran versions (amd.f and amdbar.f) * parameters added (dense row/column detection, aggressive absorption) * MATLAB mexFunction added Jan, 1996: * amdbar.f posted at http://www.netlib.org (with a restricted License) * amd.f appears as MC47B/BD in the Harwell Subroutine Library (without the IOVFLO argument)
