           CRZT01

Function/Subroutine Documentation
   real function crzt01 (integer m, integer n, complex, dimension( lda, * ) a,
       complex, dimension( lda, * ) af, integer lda, complex, dimension( * )
       tau, complex, dimension( lwork ) work, integer lwork)
       CRZT01

       Purpose:


            CRZT01 returns
                 || A - R*Q || / ( M * eps * ||A|| )
            for an upper trapezoidal A that was factored with CTZRZF.

       Parameters
           M

                     M is INTEGER
                     The number of rows of the matrices A and AF.

           N

                     N is INTEGER
                     The number of columns of the matrices A and AF.

           A

                     A is COMPLEX array, dimension (LDA,N)
                     The original upper trapezoidal M by N matrix A.

           AF

                     AF is COMPLEX array, dimension (LDA,N)
                     The output of CTZRZF for input matrix A.
                     The lower triangle is not referenced.

           LDA

                     LDA is INTEGER
                     The leading dimension of the arrays A and AF.

           TAU

                     TAU is COMPLEX array, dimension (M)
                     Details of the  Householder transformations as returned by
                     CTZRZF.

           WORK

                     WORK is COMPLEX array, dimension (LWORK)

           LWORK

                     LWORK is INTEGER
                     The length of the array WORK.  LWORK >= m*n + m.
