MatMultTranspose
Computes matrix transpose times a vector.
Synopsis
#include "petscmat.h"
PetscErrorCode MatMultTranspose(Mat mat,Vec x,Vec y)
Neighbor-wise Collective on Mat and Vec Many br
Input Parameters
| mat | - the matrix Many br |
| x | - the vector to be multilplied Many br |
Output Parameters
y -the result Many br
Notes
The vectors x and y cannot be the same. I.e., one cannot Many brcall MatMultTranspose(A,y,y). Many br
For complex numbers this does NOT compute the Hermitian (complex conjugate) transpose multiple, Many bruse MatMultHermitianTranspose() Many br
