MatFDColoringSetType#
Sets the approach for computing the finite difference parameter
Synopsis#
#include "petscmat.h"
PetscErrorCode MatFDColoringSetType(MatFDColoring matfd, MatMFFDType type)
Collective
Input Parameters#
matfd - the coloring context
type - either
MATMFFD_WPorMATMFFD_DS
Options Database Key#
-mat_fd_type - “wp” or “ds”
Note#
It is goofy that the argument type is MatMFFDType since the MatFDColoring actually computes the matrix entries
but the process of computing the entries is the same as with the MATMFFD operation so we should reuse the names instead of
introducing another one.
