# MatMultHermitianTransposeAdd

Computes v3 = v2 + A^H * v1.

### Synopsis

    #include "petscmat.h"
    PetscErrorCode MatMultHermitianTransposeAdd(Mat mat,Vec v1,Vec v2,Vec v3)

Neighbor-wise Collective on Mat

### Input Parameters

| mat | - the matrix
| v1, v2 | - the vectors

### Output Parameters

| v3 | - the result

### Notes

The vectors v1 and v3 cannot be the same. I.e., one cannot call MatMultHermitianTransposeAdd(A,v1,v2,v1).
