◆ derrqrtp()

subroutine derrqrtp ( character*3  PATH,
integer  NUNIT 
)

DERRQRTP

Purpose:
 DERRQRTP tests the error exits for the REAL routines
 that use the QRT decomposition of a triangular-pentagonal 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.
