# MatCreateHermitianTranspose

Creates a new matrix object of `MatType` `MATHERMITIANTRANSPOSEVIRTUAL` that behaves like A’*

## Synopsis

    #include "petscmat.h"
    PetscErrorCode MatCreateHermitianTranspose(Mat A, Mat *N)

Collective

## Input Parameter

- A - the (possibly rectangular) matrix

## Output Parameter

- N - the matrix that represents A’*

## Note

The Hermitian transpose A’ is NOT actually formed! Rather the new matrix object performs the matrix-vector product, `MatMult()`, by using the `MatMultHermitianTranspose()` on the original matrix
