 *******************************************************************************
 *
 * @param[in] uplo
 *          Specifies which elements of the matrix are to be set

 *          = ChamLower: STRICT Lower part of A is set to alpha;
 *          = ChamUpperLower: ALL elements of A are set to alpha.
 *          Not LAPACK Compliant.
 *
 * @param[in] M
 *          The number of rows of the matrix A.  M >= 0.
 *
 * @param[in] N
 *         The number of columns of the matrix A.  N >= 0.
 *
 * @param[in] alpha
 *         The constant to which the elements are to be set.
 *
 * @param[in,out] A
 *         On entry, the M-by-N tile A.
 *         On exit, A has been set to alpha accordingly.
 *
 * @param[in] LDA
 *         The leading dimension of the array A.  LDA >= max(1,M).
