MatMatMultTranspose

 Performs Matrix-Matrix Multiplication C=A^T*B.

Synopsis

#include "petscmat.h" 
PetscErrorCode PETSCMAT_DLLEXPORT MatMatMultTranspose(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 SeqAIJ matrices and classes which inherit from SeqAIJ. C will be of type MATSEQAIJ.
