[sage-support] Embed Cells

Dears members, I like use the SAGE to embed any code (example below). But I want linked two cells using this instruction but this not work. How I will be able to fix this?. For example I trying call from "compute" cel

[sage-support] Boolean Function

Dear all, I have a Boolean polynomial f with huge degree & variables. Also it has huge number of monomials. I want to delete all monomials from f with degree greater than 20. For that I have written the following approach. V=BooleanPolynomialRing(4,['r%d'%(i) for i in range(4)]) V.inject_variab

Hello, I am trying to install the Biopython module to sage's python installation. I am running sage 5.0, which seems to be the latest version with a OSX 10.4 binary. I am attempting to build biopython as follows: sage --python setup.py build but apparently there are some issues with gcc and sa

Re: [sage-support] right_kernel()

I ask this because I am study McEliece Cryptosystem. And to get the generator matrix of Goppa code I am using the right_kernel() instruction Krnl = H.right_kernel(); but I get always these form. The parity check matrix is building using the matrix T, V and D. How I will be able to get generator m

[sage-support] Group action

Hi guys, I have the following setting: Given a finite subgroup G of GL_\C(n) of order k, acting on C[x_1,...,x_n] by multiplication with (potenz of a ) k-th root of unity. What is the best way, to translate this setting to sage? In the end I'm interested into the ring of invariants under G and it'
