The size of DNF is exponential in the number of variables, so it’s not surprising it is slower for expressions with many variables. CNF is the more standard form that scales well with the size of the expression. Aaron Meurer On Sat, Jul 13, 2019 at 2:55 PM Oscar Benjamin wrote: > Can you show

Oscar, That does seem to do what I want ... I think. What's the difference between this and Chris Smith's answer? I think I made a symbolic equation between symbols. Didn't you make a *pythonic* assignment? Then python did the right thing when using the multiplication operation '*' (by

Thank you, that looks cool. I think some of the stuff here would be useful to integrate into SymPy Gamma https://github.com/sympy/sympy_gamma. Aaron Meurer On Fri, Jul 5, 2019 at 8:51 PM Tomasz Pytel wrote: > > Hi all, an introduction first as requested per etiquette: I have been > programming

I would suggest installing Python via Anaconda. That will include matplotlib as well as many other tools that are useful when working with SymPy, such as jupyter. Aaron Meurer On Fri, Jul 12, 2019 at 8:41 AM David Bailey wrote: > > (I forgot to send this reply to the group) > On 12/07/2019

Hi Tanvi, It's great that you want to contribute! Take a look here (I guess you already did): https://github.com/sympy/sympy/wiki/introduction-to-contributing Every part of SymPy can be improved in some way. You mention matrices - there is a lot of work going on for matrices and many issues:
