MatMultHermitianTranspose
Computes matrix Hermitian transpose times a vector.
Synopsis
#include "petscmat.h"
PetscErrorCode MatMultHermitianTranspose(Mat mat,Vec x,Vec y)
Neighbor-wise Collective on Mat
Input Parameters
| mat | - the matrix
|
| x | - the vector to be multilplied
|
Output Parameters
y -the result
Notes
The vectors x and y cannot be the same. I.e., one cannot
call MatMultHermitianTranspose(A,y,y).
Also called the conjugate transpose, complex conjugate transpose, or adjoint.
For real numbers MatMultTranspose() and MatMultHermitianTranspose() are identical.
