+/*  ======= */
+
+/*  ZLANHT  returns the value of the one norm,  or the Frobenius norm, or */
+/*  the  infinity norm,  or the  element of  largest absolute value  of a */
+/*  complex Hermitian tridiagonal matrix A. */
+
+/*  Description */
+/*  =========== */
+
+/*  ZLANHT returns the value */

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

+/*              ( normI(A),         NORM = 'I' or 'i' */

+/*              ( 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 */
+/*  squares).  Note that  max(abs(A(i,j)))  is not a consistent matrix norm. */
