Hi Jason,
Setting axes_pad=.1 does work. Thanks! However, I tried your
codes in the previous email. The resulting graph has nodes "clump
together". I guess the problem is with the value 1.5. When I changed
that to a smaller value say .05 then things work just fine. Even
though, sqrt(area/pi)

Thanks for the reply.
Is it a bug of SAGE 4.1.2 or just the Mac distribution? I guess my
question is if I upgrade SAGE to the latest version on my linux
machine, will I get the same problem?

I am using SAGE 4.1.2 notebook on firefox on a Mac.
k=graphs.CompleteGraph(6)
show(k)
displays K_6 but the vertices got truncated. I don't have this problem
on a linux machine running SAGE 4.1.1 notebook on firefox.
Any help?
I would like to include the pic but I don't see how on using this

I want to take the expression sqrt(16) from a function parameter and
return the sqrt(16) not 4. Is this possible?
Thanx

Here's another case that was working in the tinyMCE cell in Sage 4.0,
produces the error "Couldn't find \end for begin{cases}" in Sage 4.1.2,
but works in a normal (html) cell:
%html
For the potential defined by:$$ V(x) = \begin{cases}
0 & 0 \leq x \leq a\cr
\infty & x<0, x > a
\end{cases}$$
I have a sage script that generates some graphs

I get everything I expect ... plus a message

If I "save & quit" the worksheet, then

Here's a benchmark (the first thing I tried):
sage: a = random_m
I frequently shift-click over a cell and define my problems over the
cell using Latex. On importing my old work sheets most of those look
fine. Arrays that are 1X2 are fine however all of the 2x2 arrays
don't wwork in the html cell. If I include the same Latex code inside
my cell using html it

Generally I think numpy's numerical linear algebra is comparable to
matlab's.

Currently, GAP is started with the following command:
sage: gap._Expect__command
'gap -r -L /home/mike/.sage//gap/workspace-2869469835351106948 -b -p
-T -o G /opt/sage/data//extcode/gap/sage.g'
One of our Sage users want to make computations with Gap, from inside Sage.
So his commands are:
>sage
>gap.console()
then he can read his Gap program, start to run it, but the program
aborts by lack of memory.
Classically, he uses gap directly, by typing:
> gap -o 4G (to get 4 Giga Bytes).

not really, at least not that i'm aware of. you should ask this at
numpy/scipy since they are much more similar to matlab ... (these
libraries are part of sage)
basically, python is slower in some respect, e.g. loops, since they
involve much more complex objects (i.e. python objects!). on the othe

I don't know about Matlab. But there is
http://www.sagemath.org/tour-benchmarks.html
which is Sage vs. Magma. So, if nothing else is available, it might be
better than nothing.

Hi all,
I am preparing a presentation of SAGE for my department and I wanted
to illustrate it with few comparisons with other computer packages
(speed, simplicity of use, semantics). Many people in my department
work with Matlab and I wanted to compare speed. Is there any set of
benchmarks of SAG
Ok, thanks for the answer. I'm in Montevideo, Uruguay. The University
i'm talking about is "Universidad Católica del Uruguay Dámaso Antonio
Larrañaga" (the Catholic University of Uruguay). We use either Sage or
Maxima (whatever the wants to use) as a tool for Calculus 2, still we
get to learn both
Hi Burcin,
I found a work around in my case:
model_sol1_l=lambda x:exp(x)**sol1_l[a]*exp(sol1_l[b])
instead of
>model_sol1_l(I)=model_exp.subs(sol1_l)
Then it is at least possible to call the function, but the arguments
have to be of real type or floats
Greets and thanks,
Stefan

Hi,
something does not work anymore in my notebook (with version 4.1.2
ubuntu 64bit):
var('a,b,c,I')
model(I)=a*I+b
model_exp = exp(I)**a*(b)
sol1_l={b: 5.0, a: 1.1}
model_sol1_l(I)=model_exp.subs(sol1_l)
The notebook hangs-up. It's critical on the parameter a, if you change
it to 1.0 it's o.
