subroutine zerrqrt	(	character*3	PATH,
		integer	NUNIT
	)

ZERRQRT

Purpose:

 ZERRQRT tests the error exits for the COMPLEX*16 routines
 that use the QRT decomposition of a general matrix.

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.
