[sage-devel] Re: Symbolic Matrix Calculus in Sagemath

Hello, Sage's symbolic support for matrices is limited. However, Sage contains packages that may be used instead, like SymPy. For their matrix expression / equation solving capabilities see http://docs.sympy.org/latest/modules/matrices/expressions.html

[sage-devel] Coercion about finite field extensions, again

Hi, >From a discussion last year, I know that creation of finite fields with generator names is different from without generator names. But still the following is counter-intuitive. sage: k=GF(4) sage: K=k.extension(3, name='a') sage: k.is_subring(K) False sage: L=k.extension(3) sage:

I don't use Sage. I use Maxima. What you propose sounds trivial and boring, at least to me. If you want to figure out how to support block matrices and operations on them, that would be more of a challenge, and maybe of some use in the world of linear algebra, proofs, and whatnot. ( RJF On

Re: [sage-devel] build fail on Fedora 26: cannot touch...: Permission denied

Thanks. Come to think of it, I started using "sudo make" exactly for the reason you say, but it never actually occurred to me to draw a clear distinction for when I should/shouldn't elevate. On Tuesday, November 7, 2017 at 9:01:53 AM UTC-5, Michael Orlitzky wrote: > > On 11/06/2017 09:54 PM,

[sage-devel] Symbolic Matrix Calculus in Sagemath

Hi everyone! I am a final year student of computer science. I am thinking of creating a package for symbolic matrix calculus in sage as final year project. I would like to implement these identities and simplification rules for matrix

Re: [sage-devel] Re: Sage Days next July in Zaragoza (Spain)

Yes, I think it mostly means writing your code in a pip-installable way. I agree that it is an incompatible approach with the idea of merging the code into the sage library itself. However, in some cases it might make sense to have a pip package instead of merging. So, maybe we can leave some
