+/*  n by n band matrix  A,  with kl sub-diagonals and ku super-diagonals. */
+
+/*  Description */
+/*  =========== */

+/*              ( normF(A),         NORM = 'F', 'f', 'E' or 'e' */
+
+/*  where  norm1  denotes the  one norm of a matrix (maximum column sum), */
+/*  normI  denotes the  infinity norm  of a matrix  (maximum row sum) and */
+/*  normF  denotes the  Frobenius norm of a matrix (square root of sum of */
