MatSeqSBAIJSetColumnIndices

 Set the column indices for all the rows in the matrix.

Synopsis

#include "petscmat.h" 
int MatSeqSBAIJSetColumnIndices(Mat mat,int *indices)

Input Parameters

mat - the SeqSBAIJ 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 MatCreateSeqSBAIJ().

MUST be called before any calls to MatSetValues()
