MatInvertBlockDiagonal#
Inverts the block diagonal entries.
Synopsis#
#include "petscmat.h"
PetscErrorCode MatInvertBlockDiagonal(Mat mat, const PetscScalar *values[])
Collective; No Fortran Support
Input Parameter#
mat - the matrix
Output Parameter#
values - the block inverses in column major order (FORTRAN-like)
Notes#
The size of the blocks is determined by the block size of the matrix.
The blocks never overlap between two MPI processes, use MatInvertVariableBlockEnvelope() for that case
The blocks all have the same size, use MatInvertVariableBlockDiagonal() for variable block size
