MatMatMult

Performs Matrix-Matrix Multiplication C=A*B.

Synopsis

#include "petscmat.h" 
PetscErrorCode MatMatMult(Mat A,Mat B,MatReuse scall,PetscReal fill,Mat *C) 
Collective on Mat

Input Parameters

A - the left matrix
B - the right matrix
scall - either MAT_INITIAL_MATRIX or MAT_REUSE_MATRIX
fill - expected fill as ratio of nnz(C)/(nnz(A) + nnz(B))

Output Parameters

C -the product matrix

Notes

C will be created and must be destroyed by the user with MatDestroy().

This routine is currently only implemented for pairs of AIJ matrices and classes which inherit from AIJ. C will be of type MATAIJ.
