MatMultHermitianTranspose#

Computes matrix Hermitian transpose times a vector.

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 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.
