Running CHOLMOD tests. diary cholmod_test_13-Dec-2006_18-56-31.txt CHOLMOD_TEST test the CHOLMOD mexFunctions Example: cholmod_test(nmat) The UFget interface to the UF sparse matrix collection is required. nmat is optional. If present, it is the # of matrices used in tests 0, 8, 10, 11, 12, and 12. tests 14 and 15 use 2*nmat matrices. default nmat is 50. cholmod_demo: run tests on a few random matrices graph_demo: graph partitioning demo test0: test most CHOLMOD functions test1: test sparse2 test2: test sparse2 test3: test sparse on int8, int16, and logical test4: test cholmod2 with multiple and sparse right-hand-sides test5: test sparse2 test6: test sparse with large matrix, both real and complex, compare w/MATLAB test7: test sparse2 test8: order many sparse matrices, test symbfact2, compare amd and metis test9: test metis, etree, bisect, nesdis test10: test cholmod2's backslash on real and complex matrices test11: test analyze, compare CHOLMOD and MATLAB, save results in Results.mat test12: test etree2 and compare with etree test13: test cholmod2 and MATLAB on large tridiagonal matrices test14: test metis, symbfact2, and etree2 test15: test symbfact2 vs MATLAB test16: test cholmod2 on a large matrix test17: test lchol on a few large matrices test18: test cholmod2 on a few large matrices test19: look for NaN's from lchol (caused by Intel MKL 7.x bug) test20: test symbfact2, cholmod2, and lu on a few large matrices test21: test cholmod2 on diagonal or ill-conditioned matrices test22: test chol and chol2 and singular and indefinite matrices test23: test chol and cholmod2 on the sparse matrix used in "bench" test24: test sdmult test25: test sdmult on a large matrix test26: test logical full and sparse matrices test27: test nesdis See also test0, test1, ... test28.

Random matrices are not good test cases, but they are easily generated. It also compares CHOLMOD and MATLAB on the sparse matrix problem used in the MATLAB BENCH command. See CHOLMOD/MATLAB/Test/test_all.m for a lengthy test using matrices from the UF sparse matrix collection.
