+
+/*  SPOCON estimates the reciprocal of the condition number (in the */

+/*  Cholesky factorization A = U**T*U or A = L*L**T computed by SPOTRF. */

+/*  An estimate is obtained for norm(inv(A)), and the reciprocal of the */
+/*  condition number is computed as RCOND = 1 / (ANORM * norm(inv(A))). */
