* Purpose\n\
* =======\n\
*\n\
* CLASET initializes a 2-D array A to BETA on the diagonal and\n\
* ALPHA on the offdiagonals.\n\
*\n\n\
* Arguments\n\
* =========\n\
*\n\
* UPLO (input) CHARACTER*1\n\
* Specifies the part of the matrix A to be set.\n\
* = 'U': Upper triangular part is set. The lower triangle\n\
* is unchanged.\n\
* = 'L': Lower triangular part is set. The upper triangle\n\
* is unchanged.\n\
* Otherwise: All of the matrix A is set.\n\
*\n\
* M (input) INTEGER\n\
* On entry, M specifies the number of rows of A.\n\
*\n\
* N (input) INTEGER\n\
* On entry, N specifies the number of columns of A.\n\
*\n\
* ALPHA (input) COMPLEX\n\
* All the offdiagonal array elements are set to ALPHA.\n\
*\n\
* BETA (input) COMPLEX\n\
* All the diagonal array elements are set to BETA.\n\
*\n\
* A (input/output) COMPLEX array, dimension (LDA,N)\n\
* On entry, the m by n matrix A.\n\
* On exit, A(i,j) = ALPHA, 1 <= i <= m, 1 <= j <= n, i.ne.j;\n\
* A(i,i) = BETA , 1 <= i <= min(m,n)\n\
*\n\
* LDA (input) INTEGER\n\
* The leading dimension of the array A. LDA >= max(1,M).\n\
