Dear All,
during development of a package, I changed the layout. When I started,
I had a module mtx on top level (hence, "import mtx" was possible),
but now it is a sub-module (hence, "import pGroupCohomology.mtx" is
needed).
Problem: I saved some data in the old layout, and now I would like to
I think one of your problems was that the definition of L2 was
illegal since it ran into an out of range index problem. (In Python,
all lists start at 0.)
There may be better ways but, in any case, the following works.
Note I had to change the definition of L2 so that you would not get an error:
Dear all,
How can I get sage to solve a simple equation such as the one below?

| Sage Version 4.0.2, Release Date: 2009-06-18 |
| Type notebook() for the GUI, and license() for information.|
Update:
In maxima, I simply have to answer 'no' to the question whether n is an
integer and I obtain the solution. How can I pass the 'no' to maxima
through sage??

Hello Simon,
you could try:
import pGroupCohomology.mtx as mtx
Here is an example with sage and os.path:
sage: import os.path
sage: os.path
sage: os.path.a
os.path.abspath os.path.altsep
sage: import os.path as path
sage: path.a
path.abspath path.altsep
After the imports imports os.path and

This is one of the things that I tried, but it didn't help. When
loading a pickle of some class instance from mtx, it was still
complaining.
Probably, in the long run, the easiest is to te

I think there is definitely a bug in the __init__ method of the
Expression class.
Probably it has not been tracked down because this method is quasi
never used in the new version of symbolics. However, it raises
problems when one wants to derive a suclass from Expression.
The bug is described in

I would like to sample from a multinomial distribution.
What's wrong in the following statements in sage 4.0.1?
>>> import numpy.random
>>> numpy.random.multinomial(10, [.5,.5], size=20)
Thank you

I'm trying to profile my code using "prun" like the tutorial says.
However, I can't get it to work. For example a command like this:
%prun plot(x,0,2)
gives this error:
Syntax Error:
%prun plot(x,0,2)
and this:
prun plot(x,0,2)
gives this error:

Hello list,
I found a problem with integrate, look at the following sequence:
sage: integrate(sin(x)/(cos(x))^2,x)
1/cos(x)
It's ok -
Now I try to add an interval:
sage: integrate(cos(x)/(sin(x))^2,x,pi/6,pi/4)
