# MatIsHermitianKnown

Checks the flag on the matrix to see if it is hermitian.

### Synopsis

    #include "petscmat.h"
    PetscErrorCode MatIsHermitianKnown(Mat A,PetscBool *set,PetscBool *flg)

Not Collective

### Input Parameter

| A | - the matrix to check

### Output Parameters

| set | - if the hermitian flag is set (this tells you if the next flag is valid)
| flg | - the result

Note: Does not check the matrix values directly, so this may return unknown (set = PETSC_FALSE). Use MatIsHermitian() if you want it explicitly checked
