           DRZT02

Function/Subroutine Documentation
   double precision function drzt02 (integer m, integer n, double precision,
       dimension( lda, * ) af, integer lda, double precision, dimension( * )
       tau, double precision, dimension( lwork ) work, integer lwork)
       DRZT02

       Purpose:


            DRZT02 returns
                 || I - Q'*Q || / ( M * eps)
            where the matrix Q is defined by the Householder transformations
            generated by DTZRZF.

       Parameters
           M

                     M is INTEGER
                     The number of rows of the matrix AF.

           N

                     N is INTEGER
                     The number of columns of the matrix AF.

           AF

                     AF is DOUBLE PRECISION array, dimension (LDA,N)
                     The output of DTZRZF.

           LDA

                     LDA is INTEGER
                     The leading dimension of the array AF.

           TAU

                     TAU is DOUBLE PRECISION array, dimension (M)
                     Details of the Householder transformations as returned by
                     DTZRZF.

           WORK

                     WORK is DOUBLE PRECISION array, dimension (LWORK)

           LWORK

                     LWORK is INTEGER
                     length of WORK array. LWORK >= N*N+N*NB.
