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
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
