- offdiagonals.

- 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.
-
- M (input) INTEGER
- On entry, M specifies the number of rows of A.
-
- N (input) INTEGER
- On entry, N specifies the number of columns of A.
-
- ALPHA (input) COMPLEX
- All the offdiagonal array elements are set to ALPHA.
-
- BETA (input) COMPLEX
- All the diagonal array elements are set to BETA.
-
- A (input/output) COMPLEX 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) INTEGER
- The leading dimension of the array A. LDA >= max(1,M).
