# MatCholeskyFactorNumeric

Performs numeric Cholesky factorization of a symmetric matrix. Call this routine after first calling MatCholeskyFactorSymbolic().

### Synopsis

    #include "petscmat.h"
    PetscErrorCode MatCholeskyFactorNumeric(Mat fact,Mat mat,const MatFactorInfo *info)

Collective on Mat

### Input Parameters

| fact | - the factor matrix obtained with MatGetFactor()
| mat | - the initial matrix
| info | - options for factorization
| fact | - the symbolic factor of mat

### Notes

Most users should employ the simplified KSP interface for linear solvers instead of working directly with matrix algebra routines such as this. See, e.g., KSPCreate().

### See Also

MatCholeskyFactorSymbolic(), MatCholeskyFactor(), MatLUFactorNumeric()

Developer Note: fortran interface is not autogenerated as the f90 interface defintion cannot be generated correctly [due to MatFactorInfo]
