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). Author: Univ. of Tennessee Univ. of California Berkeley Univ. of Colorado Denver NAG Ltd.
