My piece of code for rational interpolation

[Thomas Baruchel]

I like very much the rinterp function from the FriCAS computer algebra system.

For that reason, I adapted it for Sympy; I think it would be nice to have it with other

interpolation functions and as far as I know it doesn't exist yet in Sympy.

Would you consider adding it to Sympy?

My code is at https://github.com/baruchel/numerical-routines/blob/master/sympy/rinterp.py

And (as told in the docstring) I adapted it from the algorithm described at: http://axiom-wiki.newsynthesis.org/RationalInterpolation

Best regards, tb.

Hi Thomas,

Thanks a lot for your code. That would indeed be a great addition to SymPy.

Just submit us a GitHub Pull Request and other people will help you
integrate it. It will also have to have a test.

If you have any questions, please ask.
