I have a set of tabulated data of the form (x,y,z) with z = f(x) + g(y) and the form of f, g is unknown. I would like to perform a simultaneous interpolation for f(x) and g(y), ideally using splines of some order. Is there any existing package to do this in Python? Apologies in advance if this has been already posted.

    Hi Johnny, this is not the place to ask this kind of question, have a look on the tour section! By the way by simply googling fitting python on google yu will find your answer (numpy, scipy, scikit, etc..) – Matteo Peluso Jul 02 '19 at 10:00
  • Hi, Thanks for your comment. I will stop here then. Just for reference, I cannot see the difference between my question and numerous similar posts, e.g here: https://stackoverflow.com/questions/6238250/multivariate-spline-interpolation-in-python-scipy – Johnny Jul 02 '19 at 11:28
