Well using 4 points to interpolate the curve that goes between the
two inner points should guarantee the absence of discontinuities in
the first (and second?) derivative; that should be the purpose. Now
if there actually are discontinuities then there must be some trivial
error in the equation, no????
Or am I missing something???
