NAME

       LAPACK-3  -  computes the product U * U**H or L**H * L, where the triangular factor U or L
       is stored in the upper or lower triangular part of the array A

SYNOPSIS

       SUBROUTINE ZLAUU2( UPLO, N, A, LDA, INFO )

           CHARACTER      UPLO

           INTEGER        INFO, LDA, N

           COMPLEX*16     A( LDA, * )

PURPOSE

       ZLAUU2 computes the product U * U**H or L**H * L, where the triangular factor U  or  L  is
       stored in the upper or lower triangular part of the array A.
        If UPLO = 'U' or 'u' then the upper triangle of the result is stored,
        overwriting the factor U in A.
        If UPLO = 'L' or 'l' then the lower triangle of the result is stored,
        overwriting the factor L in A.
        This is the unblocked form of the algorithm, calling Level 2 BLAS.

ARGUMENTS

        UPLO    (input) CHARACTER*1
                Specifies whether the triangular factor stored in the array A
                is upper or lower triangular:
                = 'U':  Upper triangular
                = 'L':  Lower triangular

        N       (input) INTEGER
                The order of the triangular factor U or L.  N >= 0.

        A       (input/output) COMPLEX*16 array, dimension (LDA,N)
                On entry, the triangular factor U or L.
                On exit, if UPLO = 'U', the upper triangle of A is
                overwritten with the upper triangle of the product U * U**H;
                if UPLO = 'L', the lower triangle of A is overwritten with
                the lower triangle of the product L**H * L.

        LDA     (input) INTEGER
                The leading dimension of the array A.  LDA >= max(1,N).

        INFO    (output) INTEGER
                = 0: successful exit
                < 0: if INFO = -k, the k-th argument had an illegal value
