MatSolverFn

Function type for the factor-creation callback registered with MatSolverTypeRegister(), used by MatGetFactor() to allocate a factored matrix of a particular MatSolverType and MatFactorType

Synopsis

PETSC_EXTERN_TYPEDEF typedef PetscErrorCode MatSolverFn(Mat, MatFactorType, Mat *);

Synopsis

#include <petscmat.h>
PetscErrorCode MatSolverFn(Mat A, MatFactorType ftype, Mat *F)

Calling Sequence

• A - the matrix to be factored

• ftype - the kind of factorization requested (e.g. MAT_FACTOR_LU, MAT_FACTOR_CHOLESKY)

• F - on output, the newly created factor Mat of the appropriate MatType for the solver
