Python package for numerical derivatives and partial differential equations in any number of dimensions.
Instead of FinDiff using central coefficients whenever possible and switching to backward or forward coefficients if not enough points are available on either side, allow the user to specify a...
Neat FD solver! I wonder how to define a nonlinear differential operator, e.g., u * du/dx, in Burgers equation?
Hi, is it possible to generate derivatives of multi dimensional coordinates, for example curvilinear (2d) latitude longitude grids? I have tried the following example which does not work: lat =...
I have a vector problem with 5 components. I would like to calculate a full set of derivatives for a given pair of points. Ideally up to order 4. The...

Hi, any intentions to make findiff xarray/dask compatible? this would make it easier to distribute tasks on a cluster. Not sure how much work this involves of course...
Hi How would you go about to set two boundary conditions on the same border? For instance in you example with the 1D forced harmonic oscillator with friction to have...
As the derivative of a given numpy array has the same size as the initial array, it could be worth mentioning how the differentiation switches between the backwards/forwards/centered scheme. Looking...
I am trying to calculate higher accuracy derivatives in 3D, however it takes extremely long time. Is there any suggestions to solve this issue ``` offsets = list(product(range(-4,5), repeat=3)) stencil...
The latest PyPI build is v9.2.0, but the conda-forge build is v0.8.9
