MatMatMultNumeric
Performs the numeric matrix-matrix product. Call this routine after first calling MatMatMultSymbolic().
Synopsis
#include "petscmat.h"
PetscErrorCode MatMatMultNumeric(Mat A,Mat B,Mat C)
Neighbor-wise Collective on Mat
Input Parameters
| A | - the left matrix
|
| B | - the right matrix
|
Output Parameters
C -the product matrix, which was created by from MatMatMultSymbolic() or a call to MatMatMult().
Notes
C must have been created with MatMatMultSymbolic().
This routine is currently implemented for
- pairs of AIJ matrices and classes which inherit from AIJ, C will be of type MATAIJ.
- pairs of AIJ (A) and Dense (B) matrix, C will be of type Dense.
- pairs of Dense (A) and AIJ (B) matrix, C will be of type Dense.
