MatRARtNumeric
Computes the matrix product C = R * A * R^T
Synopsis
#include "petscmat.h"
PetscErrorCode MatRARtNumeric(Mat A,Mat R,Mat C)
Neighbor-wise Collective on Mat
Input Parameters
| A | - the matrix
|
| R | - the projection matrix
|
Output Parameters
C -the product matrix
Notes
C must have been created by calling MatRARtSymbolic and must be destroyed by
the user using MatDestroy().
This routine is currently only implemented for pairs of AIJ matrices and classes
which inherit from AIJ. C will be of type MATAIJ.
