I beg your pardon. I never implemented the __call__ interface for the linear
interpolator or the linear interpolation for "unstructured" query points.
However, the interface for evaluating on a grid is there:

  LinearInterpolator(triangulation, z)[[ystart:ystop:ysteps*1j,
    xstart:xstop:xsteps*1j]
