cerrps()

subroutine cerrps	(	character*3	PATH,
		integer	NUNIT
	)

CERRPS

Purpose:

 CERRPS tests the error exits for the COMPLEX routines
 for CPSTRF..

Parameters

[in]	PATH	PATH is CHARACTER*3 The LAPACK path name for the routines to be tested.
[in]	NUNIT	NUNIT is INTEGER The unit number for output.
