zlaset.f-SYNOPSIS

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