Re: [sympy] Re: What is out there for SymPy code generation / optimizing compiler effort?

This is a great project. Is there a plan to incorporate CSE in this tool? For my application, the equation is extremely long, typically containing several thousands of terms. The Fortran codes generated by codegen exceed the continuation line limit of Intel Fortran compiler and have to be

Hi Jason, Thank you for the explanation. It really helped me. So, basically we want to start it, firstly, by creating a module which would deal with the mathematical operations performed on Singularity Functions. After this whole module is prepared, we would focus on how to use this module

[sympy] Re: Solveset in Symengine

Solveset is only present in the development and it will be available in 1.0 release, I expect the new users to uncover more bugs in solveset. By not being "mature" enough I mean that you can expect to see significant changes in the internal structure of solveset. In the mean time you can focus on

1) What exactly do you mean by "mature" here? 2) Sets Module would definitely be have to be implemented before solveset is started, atleast a basic version of it. 3) Also what polynomial algorithms would be necessary for solveset? On Fri, 26 Feb 2016 at 22:58 Harsh Gupta

Hi Akash, 1.) Sets module is clearly is a dependence for the solveset module, the output of solveset of set and the module also make heavy use of a lot of functionalities of Sets including intersection, union and especially imageset. SymPy's set are **very** flexible and we aim to have the

Re: [sympy] Re: GSoC idea for a project: holonomic functions

Does manipulating holonomic functions require solving linear systems with rational function coefficients, or are there more direct methods? I ask because if it does a GSoC project for this for SymPy may require improving SymPy's matrices to support working over rational function domains. Aaron

[sympy] Re: GSoC 2016: Singularity Functions

Sampad, Yes the primary use case for these singularity functions will be beam bending problems. But the singularity functions themselves should be implemented in a purely mathematical way without reference to beams. So there should be a module for these functions that allows you to work with them
