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 and Vec

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.
