[sage-support] Embed Cells

[Juan Grados]

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" cell the function Hola() in the
cell "mycell".


$(function () {
// Make the div with id 'mycell' a Sage cell
sagecell.makeSagecell({inputLocation: '#mycell',

   evalButtonText: 'Evaluate'});
// Make *any* div with class 'compute' a Sage cell
sagecell.makeSagecell({inputLocation: 'div.compute',
   linked: true,
   evalButtonText: 'Evaluate'});
});



def Hola():
print "Hola"



Hola()

[sage-support] Re: Problem installing python module to sage in Mac OSX 10.4

Some thoughts:
 
We have much more recent binaries for PPC machines on 10.4, but you are 
right that we don't have a buildbot for making binaries on a 10.4 Intel box.

Actually, you should be able to build Sage from source if you have gcc, as 
you appear to, to get a newer Sage!

What happens if you try the same thing for biopython in your Mac-provided 
Python install?

Does http://forum.tinycorelinux.net/index.php?topic=13102.0 help?  (I 
assume not.)

[sage-support] Boolean Function

[Santanu Sarkar]

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_variables()
f=r0+r1*r2+r1*r2*r3
print f.degree()
A=f.monomials()
g=0
for i in range(Set(A).cardinality()):
 if((A[i]).degree()>=2):
g=g+V(A[i])

f=f+g
print f

But observed that for my actual case, it is very slow. Will you
kindly give any better idea?

[sage-support] Problem installing python module to sage in Mac OSX 10.4

[mcl]

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 sage. This is the output I 
get after running that command.

How can I resolve this issue? Any ideas on what might be going wrong?

Thank you for your help.

Re: [sage-support] right_kernel()

[Juan Grados]

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 matrix in other form?



H: is a parity check matrix.
T: Toepliz
V: Vandermonde
D: Diagonal

That's not true for  the 1x2 matrix [1,0]:

sage: matrix(1,2,[1,0]).right_kernel()
Free module of degree 2 and rank 1 over Integer Ring
Echelon basis matrix:
[0 1]

The basis matrix is not of the form [I|A], for I the identity matrix.

For a *random* matrix you'll get [I|A] though.

Well... see #6743!  Thanks to massive work by Jean-Pierre Flori, we are 
essentially there.   How do you envision this working with SageTeX - inside 
Cygwin, or with Windows stuff?  (I mean, where the TeXing happens.)

I'm a bit late here, but sadly my only tip is: switch to OS X or Linux.
Which I know is not always a good option.

Until we have a working Cygwin port, I don't see any good options for
Windows. For now, the notebook is definitely the way to go.

This is a math question now. If A is n x k, and if you want to solve Ax = 
b, then b needs to be an n-dimensional vector. It sounds like you're trying 
with b of the wrong dimension.

sage: A = random_matrix(GF(2), 10, 20)
sage: b = random_vector(GF(2), 10)
sage: A \ b
(1, 0, 1, 1, 0, 0, 1, 1, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0)

[sage-support] Group action

[Johannes]

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's
representation as quotient.

bg,
Johannes
