NAME
slaset.f -

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

Function/Subroutine Documentation
subroutine slaset (characterUPLO, integerM, integerN, realALPHA, realBETA, real, dimension( lda, * )A, integerLDA)
SLASET initializes the off-diagonal elements and the diagonal elements of a matrix to given values.

Purpose:

SLASET 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 REAL
The constant to which the offdiagonal elements are to be set.

BETA

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

A

A is REAL 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).
