MatMultHermitianTranspose#
Computes matrix Hermitian-transpose times a vector \(y = A^H * x\).
Synopsis#
#include "petscmat.h"
PetscErrorCode MatMultHermitianTranspose(Mat mat, Vec x, Vec y)
Neighbor-wise Collective
Input Parameters#
mat - the matrix
x - the vector to be multiplied
Output Parameter#
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.
