NAME

       dlaset.f -

SYNOPSIS

   Functions/Subroutines
       subroutine dlaset (UPLO, M, N, ALPHA, BETA, A, LDA)
	   DLASET initializes the off-diagonal elements and the diagonal elements of a matrix to given values.

Function/Subroutine Documentation
   subroutine dlaset (characterUPLO, integerM, integerN, double precisionALPHA, double precisionBETA, double precision, dimension( lda, * )A,
       integerLDA)
       DLASET initializes the off-diagonal elements and the diagonal elements of a matrix to given values.

       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).

NAME

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

SYNOPSIS

       SUBROUTINE DLASET( UPLO, M, N, ALPHA, BETA, A, LDA )

	   CHARACTER	  UPLO

	   INTEGER	  LDA, M, N

	   DOUBLE	  PRECISION ALPHA, BETA

	   DOUBLE	  PRECISION A( LDA, * )

PURPOSE

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

ARGUMENTS

       UPLO    (input) 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       (input) INTEGER
	       The number of rows of the matrix A.  M >= 0.

       N       (input) INTEGER
	       The number of columns of the matrix A.  N >= 0.

       ALPHA   (input) DOUBLE PRECISION
	       The constant to which the offdiagonal elements are to be set.

       BETA    (input) DOUBLE PRECISION
	       The constant to which the diagonal elements are to be set.

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