+/*  real tridiagonal matrix A. */
+

+/*  =========== */
+
+/*  SLANGT returns the value */

+/*     SLANGT = ( max(abs(A(i,j))), NORM = 'M' or 'm' */

+/*              ( 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 */
