Running CHOLMOD tests.
diary cholmod_test_11-May-2007_13-29-15.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 a demo for CHOLMOD
 
  Tests CHOLMOD with various randomly-generated matrices, and the west0479
  matrix distributed with MATLAB.  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.
