> Hi there !
> I would like to improve the BicubicInterpolator (or the
> PiecewiseBicubicInterpolator) with the possibility to evaluate x, y, xy
> derivatives.
> In the deprecated BicubicSplineInterpolator it was already possibile.
> Before I start writing any lines of code I would like to know the rationale
> about removing this functionality.
> Also, do you have any suggestion or guideline ?
> I forked on github, I would like to contibute with a PR.
> Thank you in advance
