+/*  ======= */
+
+/*  SLARZ applies a real elementary reflector H to a real M-by-N */
+/*  matrix C, from either the left or the right. H is represented in the */
+/*  form */
+
+/*        H = I - tau * v * v' */
+
+/*  where tau is a real scalar and v is a real vector. */
+
+/*  If tau = 0, then H is taken to be the unit matrix. */
+
+
+/*  H is a product of k elementary reflectors as returned by STZRZF. */
+
+/*  Arguments */

+
