[sage-devel] Review request: Choeskly-for-sparse-matrices patch

Hey all, I'm very new here, so I'm unsure how this works; I submitted a patch on saturday that implements chokesly decomposition for sparse matrices by calling out to cvxopt.cholmod: https://trac.sagemath.org/ticket/13674 I'm trying to figure out how I can have the patch reviewed. I set the s

[sage-devel] How to review a ticket?

Hey all, I'm trying to learn how to review Trac tickets,and am unfortunately failing at it. I want to leave some comments on this file: https://git.sagemath.org/sage.git/diff/src/sage/homology/finite_topological_spaces.py?id=fc4c726665c7bf25c83a7fae6f04420e19086d69 which corresponds to this t

@vincent: I'm very new to sage-devel. As best as I can tell, the patch has stalled? Can/should someone else pick it up? On Mon, 18 Jan 2021, 20:24 Dima Pasechnik, wrote: > Interesting! Is there documentation about its capabilities? > > On Mon, 18 Jan 2021, 13:40 Siddhart

[sage-devel] Use SymEngine as a symbolic mathematics backend for SAGE

The SymPy project has another project called SymEngine , which aims to be a fast symbolic manipulation library. Perhaps we should move to use SymEngine as well, since it should be faster as it is native C++ code. This discussion came up during a discussi

[sage-devel] Why does sage use different URLs for push and fetch?

In "git the hard way", it asks us to setup: [user@localhost sage]$ git remote add trac git://trac.sagemath.org/sage.git -t master[user@localhost sage]$ git remote set-url --push trac g...@trac.sagemath.org:sage.git[user@localhost sage]$ git remote -vorigin git://github.com/sagemath/sage.git (

[sage-devel] Slow change-compile-test-cycle?

Hello all, I'm trying to make the error messages in src/sage/combinat/tableau.py a little more verbose. I'm finding that the change-compile-test cycle is quite slow. Even with a `make -j` (which should use all cores available, and I have 8, it takes quite a long time to build. It seems that most

[sage-devel] Correctly re-installing sage from source after removing a prior install from source?

I'd installed SAGE from source once, and then deleted the folder. I'm now trying to install SAGE again from source, this time at a /different/ location. It builds, and then finally fails with: [2021-01-09 19:20:11] SageMath version 9.3.beta5, Release Date: 2020-12-27 ERROR: The Sage installa

[sage-devel] Re: Adding support for discrete differential geometry for SAGE?

Hi, I've posted two "meta-tickets" with list out the basic discrete differential geometric objects I would be interested to add first. I tried to model it after the SageManifolds meta-ticket 1. Discrete Exterior calculus

[sage-devel] Adding support for discrete differential geometry for SAGE?

Hello, I've been learning differential geometry and discrete differential geometry for around a year now. I understand that SAGE now has a sage-manifolds which adds support for defining smooth manifolds as well as riemannian manifolds. I am interested in providing "discretized" versions of sm

Cool. I'm up for doing that. So.. I need to bring nauty using cython and call the is_isomorphic function? On Wed, Oct 7, 2015, 05:00 Dima Pasechnik wrote: > > > On Tuesday, 6 October 2015 13:35:00 UTC-7, Nathann Cohen wrote: >> >> Hello, >> >> > Hey, I've wanted to contribute to sage, and graphs

Re: [sage-devel] Nauty vs SageMath speed comparisons?

Hey, I've wanted to contribute to sage, and graphs and groups provided by sage is something I use quite often. So, I was wondering how I could help with the issue? If you'd be okay mentoring me, that'd be great :) On Tuesday, 6 October 2015 07:53:41 UTC+5:30, Stefan wrote: > > Yeah, that one d

[sage-devel] Hello, world - How can a new person help?

Hey everyone :) I've recently started using sage for graph theory and group theory. I'm a programmer as well, so I was wondering how I could help out with Sage. I have a) built sage from source b) created a Trac account c) looked at the "for beginner" issues on Trac, but all of them seem to hav
