+
+/*  Arguments */
+/*  ========= */
+
+/*  N       (input) INTEGER */
+/*          The order of the matrix A. */
+
+/*  A       (input) DOUBLE PRECISION array, dimension (LDA,N) */

+/*  LDA     (input) INTEGER */
+/*          The leading dimension of the array A.  LDA >= max(1, N). */
+
+/*  RHS     (input/output) DOUBLE PRECISION array, dimension (N). */
+/*          On entry, the right hand side vector b. */
+/*          On exit, the solution vector X. */

+/*  IPIV    (input) INTEGER array, dimension (N). */
+/*          The pivot indices; for 1 <= i <= N, row i of the */
+/*          matrix has been interchanged with row IPIV(i). */
