LAPACK  3.6.1
LAPACK: Linear Algebra PACKage
subroutine derrrfp ( integer  NUNIT)

DERRRFP

Purpose: 
 DERRRFP tests the error exits for the DOUBLE PRECISION driver routines
 for solving linear systems of equations.

 DDRVRFP tests the DOUBLE PRECISION LAPACK RFP routines:
     DTFSM, DTFTRI, DSFRK, DTFTTP, DTFTTR, DPFTRF, DPFTRS, DTPTTF,
     DTPTTR, DTRTTF, and DTRTTP
Parameters
[in]NUNIT
          NUNIT is INTEGER
          The unit number for output.
