Hi everybody ! I have an xyz grid of points. I want to interpolate and compute derivations along x, along y, and along xy.
If I understood correctly, I can’t use PiecewiseBicubicSplineInterpolator (this was my first attempt), since it interpolates into PiecewiseBicubicSplineInterpolatingFunction which doesn’t implements MultivariateDifferentiableFunction . I need a function able to return DerivativeStructure, am I right ? Then I double checked and found a deprecated BicubicSplineInterpolator. That interpolator lets me directly compute derivatives I need. Am I missing something ? How can I do what I need without using deprecated BicubicSplineInterpolator. Thank you in advance Alessandro Moscatelli
