       Purpose:


            Compute a minimum-norm solution
                min || A*X - B ||
            using the LQ factorization
                A = L*Q
            computed by CGELQF.

       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 >= M >= 0.

           NRHS

                     NRHS is INTEGER
                     The number of columns of B.  NRHS >= 0.

           A

                     A is COMPLEX array, dimension (LDA,N)
                     Details of the LQ factorization of the original matrix A as
                     returned by CGELQF.

           LDA

                     LDA is INTEGER
                     The leading dimension of the array A.  LDA >= M.

           TAU

                     TAU is COMPLEX array, dimension (M)
                     Details of the orthogonal matrix Q.

           B

                     B is COMPLEX array, dimension (LDB,NRHS)
                     On entry, the m-by-nrhs right hand side matrix B.
                     On exit, the n-by-nrhs solution matrix X.

           LDB

                     LDB is INTEGER
                     The leading dimension of the array B. LDB >= N.

           WORK

                     WORK is COMPLEX array, dimension (LWORK)

           LWORK

                     LWORK is INTEGER
                     The length of the array WORK.  LWORK must be at least NRHS,
                     and should be at least NRHS*NB, where NB is the block size
                     for this environment.

           INFO

                     INFO is INTEGER
                     = 0: successful exit
                     < 0: if INFO = -i, the i-th argument had an illegal value
