NAME
       TESTING/MATGEN/zlarge.f

SYNOPSIS
   Functions/Subroutines
       subroutine zlarge (n, a, lda, iseed, work, info)
           ZLARGE

Function/Subroutine Documentation
   subroutine zlarge (integer n, complex*16, dimension( lda, * ) a, integer
       lda, integer, dimension( 4 ) iseed, complex*16, dimension( * ) work,
       integer info)
       ZLARGE

       Purpose:


            ZLARGE pre- and post-multiplies a complex general n by n matrix A
            with a random unitary matrix: A = U*D*U'.

       Parameters
           N

                     N is INTEGER
                     The order of the matrix A.  N >= 0.

           A

                     A is COMPLEX*16 array, dimension (LDA,N)
                     On entry, the original n by n matrix A.
                     On exit, A is overwritten by U*A*U' for some random
                     unitary matrix U.

           LDA

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

           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*16 array, dimension (2*N)

           INFO

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