[sympy] Re: GSoC 2017: Lie groups in SymPy

There is a module on complex Lie algebras in SymPy that also deals with Dynkin diagrams. The possibility of adding real Lie algebras was discussed in this thread some time ago. Kalevi Suominen On Saturday, March 25, 2017 at 4:49:31 AM

Hi Gaurav, I think I shall be around for SciPy this time. I would be happy to collaborate on the tutorial. I was intending of meeting Ondřej anyways but I think we could all catch up at SciPy :) Thanking you Sumith On Tuesday, March 21, 2017 at 3:12:23 AM UTC+5:30, Aaron Meurer wrote: > > Yes,

Re: [sympy] Curious behavior of random.shuffle in Sympy Live Shell

That's an unfortunate side effect of the way SymPy Live is currently implemented. It reevaluates expressions every time it executes. In a real Python shell this would work as expected. Aaron Meurer On Sat, Mar 25, 2017 at 4:56 PM, plonter99 wrote: > Hi all, > I am new to Sympy. > Going through t

I would suggest trying to use the mechanics module first. Pick your favorite dynamics problem and make an example. You can submit these examples to the PyDy repository. Secondly, look for issues labeled with mechanics on the sympy issue tracker and give a shot at fixing one. Jason moorepants.info
