.. py:function:: bilin_inv(f, g, F, G, maxiter=7, tol=1e-07)

   Inverse bilinear interpolation

   ``f, g`` should be scalars or arrays of same shape

   ``F, G`` should be 2D arrays of the same shape

   :param f: Desired f value
   :param g: Desired g value
   :param F: Tabulated f values
   :param G: Tabulated g values
   :param maxiter: Maximum number of Newton iterations
   :param tol: Maximum residual value
   :return: A tuple ``(x, y)`` such that ``F[x, y] = f`` and ``G[x, y] = g``, when
       linearly interpolated
