dlaset.f(3)							      LAPACK							       dlaset.f(3)

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