[sage-devel] is_invertible() too slow comparing to rank() over GF(2^k)

2021-01-19 Thread a.simpl...@gmail.com
I am running Sagemath 9.1 on macOS 10.15.17 but I think this issue is more about math. Consider the following code G = GL(2^8, GF(2^8)) A = G.random_element() B = Matrix(A) %time B.is_invertible() C = Matrix(A) %time C.nrows() == C.ncols() == C.rank() The first timer returns 9s while the second

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

Just a suggestion: if you want to improve the speed of symbolic mathematics as done by Maxima, and you are no longer insisting on the use of Python, why not write in Lisp, and make Maxima faster? On Monday, January 18, 2021 at 6:58:10 AM UTC-8 dim...@gmail.com wrote: > > > On Mon, 18 Jan 2021

Ah. Reading your message closely, I think I see the problem. What you are trying to do, is not possible. If you want to give some comments about the code, you need to leave a comment on the corresponding trac ticket. You can parse code in comments using curly brackets: {{{ def foo(a, b):

You need to login somehow. You have previously logged in with your github account `gh-bollu`. This works as well. After you log in, the edit options will appear. Of course you can also create a sage account, which also lets you edit https://wiki.sagemath.org/ and maybe you prefer not to link yo
