NAME
       dlaset.f -

SYNOPSIS
   Functions/Subroutines
       subroutine dlaset (UPLO, M, N, ALPHA, BETA, A, LDA)
	   DLASET

Function/Subroutine Documentation
   subroutine dlaset (characterUPLO, integerM, integerN, double precisionALPHA, double precisionBETA, double precision, dimension( lda, * )A,
       integerLDA)
       DLASET

       Purpose:

	    DLASET initializes an m-by-n matrix A to BETA on the diagonal and
	    ALPHA on the offdiagonals.

       Parameters:
	   UPLO

		     UPLO is CHARACTER*1
		     Specifies the part of the matrix A to be set.
		     = 'U':	 Upper triangular part is set; the strictly lower
				 triangular part of A is not changed.
		     = 'L':	 Lower triangular part is set; the strictly upper
				 triangular part of A is not changed.
		     Otherwise:  All of the matrix A is set.

	   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.

	   ALPHA

		     ALPHA is DOUBLE PRECISION
		     The constant to which the offdiagonal elements are to be set.

	   BETA

		     BETA is DOUBLE PRECISION
		     The constant to which the diagonal elements are to be set.

	   A

		     A is DOUBLE PRECISION array, dimension (LDA,N)
		     On exit, the leading m-by-n submatrix of A is set as follows:

		     if UPLO = 'U', A(i,j) = ALPHA, 1<=i<=j-1, 1<=j<=n,
		     if UPLO = 'L', A(i,j) = ALPHA, j+1<=i<=m, 1<=j<=n,
		     otherwise,     A(i,j) = ALPHA, 1<=i<=m, 1<=j<=n, i.ne.j,

		     and, for all UPLO, A(i,i) = BETA, 1<=i<=min(m,n).

	   LDA

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