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

SERRRFP

Purpose: 
 SERRRFP tests the error exits for the REAL driver routines
 for solving linear systems of equations.

 SDRVRFP tests the REAL LAPACK RFP routines:
     STFSM, STFTRI, SSFRK, STFTTP, STFTTR, SPFTRF, SPFTRS, STPTTF,
     STPTTR, STRTTF, and STRTTP
Parameters
[in]NUNIT
          NUNIT is INTEGER
          The unit number for output.
