+
+/*  DGTCON estimates the reciprocal of the condition number of a real */
+/*  tridiagonal matrix A using the LU factorization as computed by */
+/*  DGTTRF. */
+
+/*  An estimate is obtained for norm(inv(A)), and the reciprocal of the */
+/*  condition number is computed as RCOND = 1 / (ANORM * norm(inv(A))). */

+/*  NORM    (input) CHARACTER*1 */
+/*          Specifies whether the 1-norm condition number or the */
