+
+/*  DGECON estimates the reciprocal of the condition number of a general */
+/*  real matrix A, in either the 1-norm or the infinity-norm, using */
+/*  the LU factorization computed by DGETRF. */
+
+/*  An estimate is obtained for norm(inv(A)), and the reciprocal of the */
+/*  condition number is computed as */
+/*     RCOND = 1 / ( norm(A) * norm(inv(A)) ). */
