MatMatMultSymbolic
Performs construction, preallocation, and computes the ij structure of the matrix-matrix product C=A*B. Call this routine before calling MatMatMultNumeric().
Synopsis
#include "petscmat.h"
int MatMatMultSymbolic(Mat A,Mat B,Mat *C)
Collective on Mat
Input Parameters
| A | - the left matrix
|
| B | - the right matrix
|
Output Parameters
C -the matrix containing the ij structure of product matrix
Notes
C will be created and must be destroyed by the user with MatDestroy().
This routine is currently only implemented for SeqAIJ type matrices.
