NAME
       zlauum.f -

SYNOPSIS
   Functions/Subroutines
       subroutine zlauum (UPLO, N, A, LDA, INFO)
	   ZLAUUM computes the product UUH or LHL, where U and L are upper or lower triangular matrices (blocked algorithm).

Function/Subroutine Documentation
   subroutine zlauum (characterUPLO, integerN, complex*16, dimension( lda, * )A, integerLDA, integerINFO)
       ZLAUUM computes the product UUH or LHL, where U and L are upper or lower triangular matrices (blocked algorithm).

       Purpose:

	    ZLAUUM 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 blocked form of the algorithm, calling Level 3 BLAS.

       Parameters:
	   UPLO

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

	   N

		     N is INTEGER
		     The order of the triangular factor U or L.  N >= 0.

	   A

		     A is 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

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

	   INFO

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