[petsc-users] Cholesky factorization

[Petar Petrovic]

Thank you very much.
Can you tell me how to set the package that is used for MatCholeskyFactor?
I need it to run for a sparse matrix so I have tried using:

#ifdef PETSC_HAVE_CHOLMOD
...
#endif

but the code inside doesn't run. Does this mean that the package is not
installed or am I supposed to do something else, use some command line
options or something? Sorry these are very basic questions, but I am new to
PETSc and I cannot seem to find examples for this.
