SYNOPSIS
   Functions/Subroutines
       subroutine dget03 (n, a, lda, ainv, ldainv, work, ldwork, rwork, rcond,
           resid)
           DGET03

Function/Subroutine Documentation
   subroutine dget03 (integer n, double precision, dimension( lda, * ) a,
       integer lda, double precision, dimension( ldainv, * ) ainv, integer
       ldainv, double precision, dimension( ldwork, * ) work, integer ldwork,

       precision resid)
       DGET03

       Purpose:


            DGET03 computes the residual for a general matrix times its inverse:
               norm( I - AINV*A ) / ( N * norm(A) * norm(AINV) * EPS ),
            where EPS is the machine epsilon.

       Parameters
           N

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

           A

                     A is DOUBLE PRECISION array, dimension (LDA,N)
                     The original N x N matrix A.

           LDA

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

           AINV

                     AINV is DOUBLE PRECISION array, dimension (LDAINV,N)
                     The inverse of the matrix A.

           LDAINV

                     LDAINV is INTEGER
                     The leading dimension of the array AINV.  LDAINV >= max(1,N).

           WORK

                     WORK is DOUBLE PRECISION array, dimension (LDWORK,N)

           LDWORK

                     LDWORK is INTEGER
                     The leading dimension of the array WORK.  LDWORK >= max(1,N).

           RWORK

                     RWORK is DOUBLE PRECISION array, dimension (N)

           RCOND

                     RCOND is DOUBLE PRECISION
                     The reciprocal of the condition number of A, computed as
                     ( 1/norm(A) ) / norm(AINV).

           RESID

                     RESID is DOUBLE PRECISION
                     norm(I - AINV*A) / ( N * norm(A) * norm(AINV) * EPS )
