   1 function c_norm = c_norm(w, a, b, v)
   2   ##
   3   ## The norm on C[a,b] induced by c_inner_product.

   5   ## INPUT:
   6   ##
   7   ##   * ``w`` -- The weight function.
   8   ##
   9   ##   * ``a`` -- The left endpoint of the interval.
  10   ##
  11   ##   * ``b`` -- The right endpoint of the interval.
  12   ##
  13   ##   * ``v`` -- The vector.

  15   ## OUTPUT:
  16   ##
  17   ## The norm of `v`; that is, the inner product sqrt(<v, v>).
