Derivative of an array in python?

Question

Currently I have two numpy arrays: x and y of the same size.

I would like to write a function (possibly calling numpy/scipy... functions if

Answer 1

The findiff project is a Python package that can do derivatives of arrays of any dimension with any desired accuracy order (of course depending on your hardware restrictions). It can handle arrays on uniform as well as non-uniform grids and also create generalizations of derivatives, i.e. general linear combinations of partial derivatives with constant and variable coefficients.
