.SH PURPOSE
ZLASET initializes a 2-D array A to BETA on the diagonal and ALPHA on the offdiagonals.
.SH ARGUMENTS
.TP 8
UPLO (input) 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.
.TP 8
M (input) INTEGER
On entry, M specifies the number of rows of A.
.TP 8
N (input) INTEGER
On entry, N specifies the number of columns of A.
.TP 8
ALPHA (input) COMPLEX*16
All the offdiagonal array elements are set to ALPHA.
.TP 8
BETA (input) COMPLEX*16
All the diagonal array elements are set to BETA.
.TP 8
A (input/output) 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)
.TP 8
LDA (input) INTEGER
The leading dimension of the array A. LDA >= max(1,M).
