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
