It's worse than I thought..I can not get python or isympy to agree that mpmath is available. Do I have something mis-installed? I am a git puller and have had no problems, until this example. Please illuminate. Thanks. Comer On Thursday, February 13, 2014 10:18:37 AM UTC-5, Comer wrote: I

[sympy] work regarding Group Theory module

Hi, I posted about my idea to implement Group Theory module in Sympy. According to the prerequisites for any GSOC aspirant, he has to post a patch/PR regarding the topic he wishes to base his GSOC project on. Now, since Sympy doesn't contain any module related to Groups, can anyone please tell

By x^2 did you mean x to the power 2? SymPy follows python convention so ^ is the xor operator. ** is used for power. -- You received this message because you are subscribed to the Google Groups sympy group. To unsubscribe from this group and stop receiving emails from it, send an email to

As part of handling infinite solutions for something like (sin(x) == 0) I have started some work in https://github.com/sympy/sympy/pull/2904. After this we will be able to have intersection of many infinite imagesets with finite sets. I think we should list out other set theoretic capabilities we

Neither qualified nor particularly well qualified to mentor this project. For me the sets module was a good example of how to cleanly represent and simplify expressions; I wasn't interested in the mathematical details of how such simplifications are accomplished. I'm more interested in

The existing group theory code is in the combinatorics module. Take a look at https://github.com/sympy/sympy/wiki/GSoC-2012-Report-Aleksandar-Makelov%3A-Computational-Group-Theory. Aaron Meurer On Wed, Feb 12, 2014 at 9:05 PM, Aditya Shah adityasha...@gmail.com wrote: Also I would like to add

That won't work with the pretty printers, though. It would be better to implement wrappers, like suggested at https://code.google.com/p/sympy/issues/detail?id=3736#c3. Aaron Meurer On Tue, Feb 11, 2014 at 11:30 PM, Chris Smith smi...@gmail.com wrote: evaluate=False is the way to do this:

For what it's worth. I personally found some value in both suggestions. I don't think I'm up to coding a complete solution, but I ended up doing enough to solve my current issue (involving some notebooks used for a study group) by making an alternate version of the latex function. -Mike On
