[sympy] Regression in 0.7.4? Infinite recursion in dsolve call

Hi everyone, after updating sympy to 0.7.4, some of our code calling dsolve seems to go into an infinite recursion and errors out with "maximum recursion depth exceeded". A simple example demonstrating the issue is the following: >>> f = Function('f') >>> t = Symbol('t') >>> dsolve(Eq(Derivativ

[sympy] GSoC 2014: PDE Solver

Hi Everyone, I am Sai Priyatham. I am currently a sophomore majoring in electrical engineering at IIT Bombay. I am interested in contributing to SymPy through GSoC 2014. I am interested in expanding PDE solver which currently supports only first order PDE's. I have had two courses in my college

Apart from that, you may need to set up your environment according to our development work flow wiki page if you haven't already done so. [1] [1] https://github.com/sympy/sympy/wiki/Development-workflow On Wed, Dec 11, 2013 at 9:46 PM, Ondřej Čertík wrote: > Hi Priyatham, > > On Wed, Dec 11,

I bisected it to commit cfad6db7172906255c26c3a082257f639bb7107c Author: Mateusz Paprocki Date: Thu Mar 21 17:24:57 2013 +0100 polys: Renamed to RealDomain to RealField. So one thing not mentioned in the release notes was that there were some changes to the way the polys handle floating p

Re: [sympy] Starting out with a project

Take a look at https://github.com/sympy/sympy/wiki/development-workflow to get your workflow setup, and then find some easy to fix issue http://code.google.com/p/sympy/issues/list?&q=label%3Aeasytofix and try to fix it. Let us know if you have any questions. Aaron Meurer On Sat, Dec 7, 2013 at 1:

Re: [sympy] Numeric differentiation

Why don't you just take the symbolic derivative and numerically solve for that? Aaron Meurer On Sat, Dec 7, 2013 at 8:22 AM, Alexander Birukov wrote: > Just wondeing about one thing. I have a function: > >

Hi Ondrej, hi Aaron, thanks for looking into this. Should I open an issue about it (or for the future: should I rather directly open an issue instead of writing a mail to the list)? Best, Marcel -- You received this message because you are subscribed to the Google Groups "sympy" group. To

Re: [sympy] Regression in 0.7.4? Infinite recursion in dsolve call

Yes, please open an issue for it. In the future, if you are sure something is a bug, open an issue. If you are not sure, you can write to the list. Aaron Meurer On Wed, Dec 11, 2013 at 2:32 PM, Marcel Stimberg wrote: > Hi Ondrej, hi Aaron, > > thanks for looking into this. Should I open an issue

[sympy] Issue migration from Google Code to GitHub

I put a call out for this on social media, but I thought I would ask here too. I now have some free time to look at migrating the issues from Google Code to GitHub. Does anyone know of any good tools to do this? Does anyone know of other projects that have done this that I can get into contact with

Re: [sympy] Issue migration from Google Code to GitHub

No helpful information from me. A meta point is that there should maybe be a mailing list for project managers. I suspect y'all have some unique concerns/views. What about stackoverflow? On Wed, Dec 11, 2013 at 7:57 PM, Aaron Meurer wrote: > I put a call out for this on social media, but I t

Thanks guys, Ondrej, I would love to meet you if I were in the campus(unfortunately I am at my home right now). I have gone through what you have suggested and I have decided to start with something small. When I searched the documentation I couldn't find a function that determines if a functio

Re: [sympy] Re: GSoC 2014: PDE Solver

Actually, there was some work done at https://github.com/sympy/sympy/pull/2551/files for trig functions. So I guess you should follow that same API, but for other types of functions. Aaron Meurer On Wed, Dec 11, 2013 at 11:18 PM, Aaron Meurer wrote: > It's been discussed at > https://code.google

It's been discussed at https://code.google.com/p/sympy/issues/detail?id=2444, but I don't think anyone's implemented it yet. Aaron Meurer On Wed, Dec 11, 2013 at 11:11 PM, Sai Priyatham Kattakinda wrote: > Thanks guys, > > Ondrej, I would love to meet you if I were in the campus(unfortunately I
