NAME
       TESTING/LIN/cget01.f

SYNOPSIS
   Functions/Subroutines
       subroutine cget01 (m, n, a, lda, afac, ldafac, ipiv, rwork, resid)
           CGET01

Function/Subroutine Documentation
   subroutine cget01 (integer m, integer n, complex, dimension( lda, * ) a,
       integer lda, complex, dimension( ldafac, * ) afac, integer ldafac,
       integer, dimension( * ) ipiv, real, dimension( * ) rwork, real resid)
       CGET01

       Purpose:


            CGET01 reconstructs a matrix A from its L*U factorization and
            computes the residual
               norm(L*U - A) / ( N * norm(A) * EPS ),
            where EPS is the machine epsilon.

       Parameters
           M

                     M is INTEGER
                     The number of rows of the matrix A.  M >= 0.

           N

                     N is INTEGER
                     The number of columns of the matrix A.  N >= 0.

           A

                     A is COMPLEX array, dimension (LDA,N)
                     The original M x N matrix A.

           LDA

                     LDA is INTEGER
                     The leading dimension of the array A.  LDA >= max(1,M).

           AFAC

                     AFAC is COMPLEX array, dimension (LDAFAC,N)
                     The factored form of the matrix A.  AFAC contains the factors
                     L and U from the L*U factorization as computed by CGETRF.
                     Overwritten with the reconstructed matrix, and then with the
                     difference L*U - A.

           LDAFAC

                     LDAFAC is INTEGER
                     The leading dimension of the array AFAC.  LDAFAC >= max(1,M).

           IPIV

                     IPIV is INTEGER array, dimension (N)
                     The pivot indices from CGETRF.

           RWORK

                     RWORK is REAL array, dimension (M)

           RESID

                     RESID is REAL
                     norm(L*U - A) / ( N * norm(A) * EPS )
