21 ZLASET initializes a 2-D array A to BETA on the diagonal and ALPHA on
22 the offdiagonals.
23
25 UPLO (input) CHARACTER*1
26 Specifies the part of the matrix A to be set. = 'U':
27 Upper triangular part is set. The lower triangle is unchanged.
28 = 'L': Lower triangular part is set. The upper triangle is
29 unchanged. Otherwise: All of the matrix A is set.
30
31 M (input) INTEGER
32 On entry, M specifies the number of rows of A.
33
34 N (input) INTEGER
35 On entry, N specifies the number of columns of A.
36
37 ALPHA (input) COMPLEX*16
38 All the offdiagonal array elements are set to ALPHA.
39
40 BETA (input) COMPLEX*16
41 All the diagonal array elements are set to BETA.
42
43 A (input/output) COMPLEX*16 array, dimension (LDA,N)
44 On entry, the m by n matrix A. On exit, A(i,j) = ALPHA, 1 <= i
45 <= m, 1 <= j <= n, i.ne.j; A(i,i) = BETA , 1 <= i <= min(m,n)
46
47 LDA (input) INTEGER
48 The leading dimension of the array A. LDA >= max(1,M).
