.PP
\fBPurpose:\fP
.RS 4

.PP
.nf
 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\&.

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

.br
\fILDA\fP 
.PP
.nf
          LDA is INTEGER
          The leading dimension of the array A\&.  LDA >= max(1,M)\&.

.br
\fIAFAC\fP 
.PP
.nf
          AFAC is COMPLEX array, dimension (LDAFAC,N)

          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\&.
