[sympy] simplify expression into summation

2014-08-01 Thread Nova Munch
hello, 2 questions related to reducing to summation using sympy: 1) lets say i have an expression (x) + (x+1) + (x+2) + (x+3) + (x+4) is there any function to help me simplify/reduce it to become summation of x over 0 to 4? along the same line: 2) lets say i have an expression (x[0]*y[0]) + (

Hi Zack, There are currently 2 students doing GSoC under CSymPy. I'm working on Extending Elementary Functions and Thilina is working on implementing Matrix Module. Here is my GSoC Proposal to give you a rough idea of stuff I'm covering as a part of my project. Mo

Just wanted to make sure this didn't forgotten! Have either of you looked into the performance loss? On Monday, July 28, 2014 5:07:21 PM UTC-7, Madison Stemm wrote: > > Alright, I've got the test code to do some performance benchmarking with > SymPy. This will run through 1742 series of sympy.so

Yes, I highly recommend using the git access if you can. And in case it isn't clear, you have to have push access to the main SymPy repo in order to be able to push to the wiki (although anyone can clone it). Aaron Meurer On Fri, Aug 1, 2014 at 6:06 PM, Tim Lahey wrote: > Ah, > > It's not easy t

Ah, It's not easy to find the details about it. It doesn't help that there's a wiki repo for SymPy (that just points to the GitHub wiki). The general syntax is, git clone https://github.com/user/project.wiki.git so for SymPy, it should be, git clone https://github.com/sympy/sympy.wiki.git

Is there another way to update the Wiki pages other than the web editor? It seems a bit tedious to update each page in the SymPy vs. pages with the same SymPy details by hand. Anyway, I've updated the SymPy vs. Sage comparison page (I didn't do the others, though). It now lists the latest vers

Hey all, So as I mentioned in the subject, I'm currently an undergrad Math/CS student, and I recently came across this package via the wiki page for GSOC 2014 ideas. It seems like there is a lot of interesting work going on in Sympy, and I was hoping to find a way to contribute. My short-term g
