MatSeqBAIJSetColumnIndices
Set the column indices for all the rows in the matrix.
Synopsis
#include "petscmat.h"
PetscErrorCode MatSeqBAIJSetColumnIndices(Mat mat,PetscInt *indices)
Input Parameters
| mat | - the SeqBAIJ matrix
|
| indices | - the column indices
|
Notes
This can be called if you have precomputed the nonzero structure of the
matrix and want to provide it to the matrix object to improve the performance
of the MatSetValues() operation.
You MUST have set the correct numbers of nonzeros per row in the call to
MatCreateSeqBAIJ(), and the columns indices MUST be sorted.
MUST be called before any calls to MatSetValues();
