NAME
       TESTING/MATGEN/clagge.f

SYNOPSIS
   Functions/Subroutines
       subroutine clagge (m, n, kl, ku, d, a, lda, iseed, work, info)
           CLAGGE

Function/Subroutine Documentation
   subroutine clagge (integer m, integer n, integer kl, integer ku, real,
       dimension( * ) d, complex, dimension( lda, * ) a, integer lda, integer,
       dimension( 4 ) iseed, complex, dimension( * ) work, integer info)
       CLAGGE

       Purpose:


            CLAGGE generates a complex general m by n matrix A, by pre- and post-
            multiplying a real diagonal matrix D with random unitary matrices:
            A = U*D*V. The lower and upper bandwidths may then be reduced to
            kl and ku by additional unitary transformations.

       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 >= 0.

           KL

                     KL is INTEGER
                     The number of nonzero subdiagonals within the band of A.
                     0 <= KL <= M-1.

           KU

                     KU is INTEGER
                     The number of nonzero superdiagonals within the band of A.
                     0 <= KU <= N-1.

           D

                     D is REAL array, dimension (min(M,N))
                     The diagonal elements of the diagonal matrix D.

           A

                     A is COMPLEX array, dimension (LDA,N)
                     The generated m by n matrix A.

           LDA

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

           ISEED

                     ISEED is INTEGER array, dimension (4)
                     On entry, the seed of the random number generator; the array
                     elements must be between 0 and 4095, and ISEED(4) must be
                     odd.
                     On exit, the seed is updated.

           WORK

                     WORK is COMPLEX array, dimension (M+N)

           INFO

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