+/*  ======= */
+
+/*  ZPBCON estimates the reciprocal of the condition number (in the */
+/*  1-norm) of a complex Hermitian positive definite band matrix using */
+/*  the Cholesky factorization A = U**H*U or A = L*L**H computed by */
+/*  ZPBTRF. */
+
+/*  An estimate is obtained for norm(inv(A)), and the reciprocal of the */
+/*  condition number is computed as RCOND = 1 / (ANORM * norm(inv(A))). */
+
+/*  Arguments */
+/*  ========= */
+
+/*  UPLO    (input) CHARACTER*1 */

+/*  KD      (input) INTEGER */
