DSMatIsHermitian

Checks if one of the DS matrices is known to be Hermitian.

#include "slepcds.h" 
PetscErrorCode DSMatIsHermitian(DS ds,DSMatType t,PetscBool *flg)

Not Collective

	ds	- the direct solver context
	t	- the requested matrix

flg

- the Hermitian flag

Does not check the matrix values directly. The flag is set according to the problem structure. For instance, in DSHEP matrix A is Hermitian.
