subroutine cerrlqtp ( character*3  path,
integer  nunit 
)

ZERRLQTP

Purpose:
 CERRLQTP tests the error exits for the complex routines
 that use the LQT 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.
