Hello,
I need to be able to evaluate an expression, where the expression is
composed of dynamically generated variables. For example, I might have
a list "var_list", a list "data_list", and an expression "exprssn".
Here
1) var_list is a list of variables, where every element in var_list
was creat

I'm on an Ubuntu 9.04 ThinkPad T41 laptop. I built my Sage install
from 3.4 source myself as there was no binary yet for this latest
Ubuntu.

Dear Minh, dear Michael,
thanks a lot.
Thanks to Minh for this simple but fine idea to compile in a command
line session!
Meanwhile the RAM I had bought has arrived and with the now available
more than 300 MB I let the compiler run once again. This time it
seemed to "freeze" at the same point
Hello all. hope all is well w/ all of u. anywho, when ever i try to

I guess you are using Sage 3.4?

Thanks - that's just what I wanted to know. Wouldn't be nice if Sage
had something like Matlab's "lookfor" command, which gives you the
name of all functions containing that substring, and a very brief
(half line) description.

It should open it read only, but let me check.

What Sage release precisely are you using, i.e. version, binary name,
etc? If i
Is there a way of searching for functions which contain a particular
string in their names? Yesterday I was trying to find the extended
Euclidean algorithm (xgcd); my search would have been trivial if I
could have searched for all functions containing the string "gcd". As
it was I found it almos

Yes, you can do them from within Cython, but it's not going to give
you the speed up that you might think / want. Making code faster is
almost entirely finding out exactly
Thanks Mike,
Is it possible to do the symbolic computations with Cython?
If not, I will wait until Sage 4.0 comes out and see what happens.

Hi all,
I am new to Sage and I don't quite understand how to convert my code
to cython code to speed up my program. I am doing a lot of symbolic
manipulations and using the PolynomialRing object. Below I have some
of my code so that you can see the types of manipulations I hope to
speed up:

Thanks for the help! The expression that I had was a result of a
previous computation and I did not realize that I had to expand the
expression and the simplify command would not multiply then cancel
common terms.

Just installed Sage on CentOS 5.3 server. Local system. I am getting
"sage-sage: line 197 6520 Illegal instruction sage-ipyth "$@" -i".
Any help would be appreciated.

It looks like this notebook no longer uses jsMath to render the result
of var('n m'), so I can't reproduce the problem you describe. I do
know that jsMath was used earlier when we were looking at the IE font
