 function ip = c_inner_product(w, a, b, v1, v2)
+  ##
+  ## The usual inner product defined on the space of continuous
+  ## functions over the interval [a,b].

+  ## INPUT:
+  ##
+  ##   * ``w`` -- The weight function.
+  ##
+  ##   * ``a`` -- The left endpoint of the interval.

+  ##   * ``b`` -- The right endpoint of the interval.

+  ##   * ``v1`` -- The first vector.

+  ## OUTPUT:
+  ##
+  ## The inner product <v1, v2>.
