Hi Alberto,
I'm currently working on a matrix viewer for the sage notebook (using
SVG). It wouldn't be too difficult to add editing features once it's
been integrated with the notebook.

Cool. The notebook integration is kinda hacky but works. The python
code outputs a bunch of html tag - an iframe with the editor and
hidden input tag with the data. The iframe takes it from there and
reads in the data. Send me an email if you need help with it.
Glad it works with Nexus One. On the
I agree that such a thing would be very convenient. I have found
myself always using something like
lattice_polytope.read_palp_matrix(r"""4 5
1 0 0 0 1
0 1 0 0 1
0 0 1 0 1
0 0 0 1 1""")
for entering matrices since it involves much less typing than usual
matrix constructors (except for the functio
Hi everyone. I have used sage for some time and it was really useful
in calculus and algebra though I made heavy use of it to deal with
matrices operations and in my opinion the process of inputting (create/
edit) matrices could be made faster and less error-prone.
The standard way to input matric
Somebody wrote [1] a Reduce (cf. [2]) interface some time ago. If it
works properly one could try to load Bergmann [3] from it. That would
give access to plenty of Groebner basis, Hilbert series, Hochschild
cohomology and many other ring theoretical methods for big families of
noncommutative algebr

Thanks for the code. From what i see, it does not inherit ideals or
groebner basis. I will try to take a look at that.

Thank you for your work.

There is a bug somewhere in the point counting code for elliptic
curves. Checked both on Linux/4.2.x and OSX-PowerPC/4.2.1. The bug
appears to be either in the PARI ellsea routine or in the SAGE
interface to it. With some more time I plan to look further and look
for an easy fix (unless someone
It worked up to the point where I got some: "Hunk #1 FAILED at 0" and
similar errors, with a final "abort: patch failed to apply"
Thanks for your help, but it looks like I need to learn more about this
mercurial before I proceed.

The only way I know is (I am kinda new to all this):
1) unzip sagenb in spkg/standard
2) go to the subfolder containing setup.py
3) SAGEPATH\sage -python setup.py develop
4) hg patch *patchname*
hope that helps.

I am trying to find the root of some test failure with the maxima interface
on the port of sage of Gentoo and I have just read the content of

If on the other hand one goes for having Sage installed on a working
installation of Cygwin (which is much more realistic option),
