   .. py:method:: _constructMatrix()

      Constructs the inequality constraint matrix G, right-hand side h, and
      upper bound u for the knapsack problem.

      :returns: Weights of items
                h (jnp.ndarray): Total capacity
                u (jnp.ndarray): Upper bound for item selection
      :rtype: G (jnp.ndarray)
