MatCholeskyFactorNumeric

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

Synopsis

#include "petscmat.h" 
int MatCholeskyFactorNumeric(Mat mat,Mat *fact)
Collective on Mat

Input Parameter

mat -the initial matrix

Output Parameter

fact -the factored matrix

Notes

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