ZLASET(3) LAPACK routine of NEC Numeric Library Collection ZLASET(3)
NAME
ZLASET
SYNOPSIS
SUBROUTINE ZLASET (UPLO, M, N, ALPHA, BETA, A, LDA)
PURPOSE
ZLASET initializes a 2-D array A to BETA on the diagonal and
ALPHA on the offdiagonals.
ARGUMENTS
UPLO (input)
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 (input)
M is INTEGER
On entry, M specifies the number of rows of A.
N (input)
N is INTEGER
On entry, N specifies the number of columns of A.
ALPHA (input)
ALPHA is COMPLEX*16
All the offdiagonal array elements are set to ALPHA.
BETA (input)
BETA is COMPLEX*16
All the diagonal array elements are set to BETA.
A (input/output)
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 (input)
LDA is INTEGER
The leading dimension of the array A. LDA >= max(1,M).
