MatKAIJSetAIJ#

Set the MATAIJ matrix describing the blockwise action of the MATKAIJ matrix

Synopsis#

#include "petscmat.h" 
PetscErrorCode MatKAIJSetAIJ(Mat A, Mat B)

Logically Collective; if the MATAIJ matrix is parallel, the MATKAIJ matrix is also parallel

Input Parameters#

A - the MATKAIJ matrix
B - the MATAIJ matrix

Notes#

This function increases the reference count on the MATAIJ matrix, so the user is free to destroy the matrix if it is not needed.

Changes to the entries of the MATAIJ matrix will immediately affect the MATKAIJ matrix.
