[sympy] Series Expansion[GSoC-19 Proposal]

2019-03-12 Thread Nabanita Dash
Greetings I would like to work this summer extending series expansion so as to improve rs_series,so that SymPy can use it as default series expansion in SymPy.I also want to work on formal power series and on limits.Below,I have summarized what I want to do. *Proposal:* 1)* Improve

How in depth do you intend to go with each of these? I'm not sure about the others but for elliptic curves at least one could potentially spend a whole summer just on it. Aaron Meurer On Tue, Mar 12, 2019 at 1:11 PM Aditya Gulati wrote: > > Thank you for your remarks and clarification. I

Thank you for your remarks and clarification. I revised my plans to better fit the educational goals. They are as follows, 1. Add S-Boxes (Substitution boxes) and P-Boxes (Permutation boxes) as they form the basis of nearly all block ciphers. Maybe add a DES function as its

Thanks for the info Jason Moore and Vishesh Mangla. I analyzed the mechanics benchmarks. Many of the commits which are increasing the computation time are related to ode, printing , matrices. I tried to find to find substitute for them. I think LU Decompositon is used in lagrange.py whose time

As I noted in #16162, it was educational purposes that drove the addition of this module in the first place so I mostly agree that additions should be few. On Monday, March 11, 2019 at 7:18:34 PM UTC-5, Aaron Meurer wrote: > > Maybe others will disagree with me, but I'd rather see things that
