Function/Subroutine Documentation¶
subroutine zlaset (characterUPLO, integerM, integerN, complex*16ALPHA, complex*16BETA, complex*16, dimension( lda, * )A, integerLDA)¶
ZLASET initializes the off-diagonal elements and the diagonal elements of a matrix to given values. Purpose:ZLASET initializes a 2-D array A to BETA on the diagonal and ALPHA on the offdiagonals.
UPLO
Author:
UPLO is CHARACTER*1 Specifies the part of the matrix A to be set. = 'U': Upper triangular part is set. The lower triangle is unchanged. = 'L': Lower triangular part is set. The upper triangle is unchanged. Otherwise: All of the matrix A is set.M
M is INTEGER On entry, M specifies the number of rows of A.N
N is INTEGER On entry, N specifies the number of columns of A.ALPHA
ALPHA is COMPLEX*16 All the offdiagonal array elements are set to ALPHA.BETA
BETA is COMPLEX*16 All the diagonal array elements are set to BETA.A
A is COMPLEX*16 array, dimension (LDA,N) On entry, the m by n matrix A. On exit, A(i,j) = ALPHA, 1 <= i <= m, 1 <= j <= n, i.ne.j; A(i,i) = BETA , 1 <= i <= min(m,n)LDA
LDA is INTEGER The leading dimension of the array A. LDA >= max(1,M).
