# 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
