21 ZLASET initializes a 2-D array A to BETA on the diagonal and ALPHA on
22 the offdiagonals.
23
24
26 UPLO (input) CHARACTER*1
27 Specifies the part of the matrix A to be set. = 'U':
28 Upper triangular part is set. The lower triangle is unchanged.
29 = 'L': Lower triangular part is set. The upper triangle is
30 unchanged. Otherwise: All of the matrix A is set.
31
32 M (input) INTEGER
33 On entry, M specifies the number of rows of A.
34
35 N (input) INTEGER
36 On entry, N specifies the number of columns of A.
37
38 ALPHA (input) COMPLEX*16
39 All the offdiagonal array elements are set to ALPHA.
40
41 BETA (input) COMPLEX*16
42 All the diagonal array elements are set to BETA.
43
44 A (input/output) COMPLEX*16 array, dimension (LDA,N)
45 On entry, the m by n matrix A. On exit, A(i,j) = ALPHA, 1 <= i
46 <= m, 1 <= j <= n, i.ne.j; A(i,i) = BETA , 1 <= i <= min(m,n)
47
48 LDA (input) INTEGER
49 The leading dimension of the array A. LDA >= max(1,M).
