This worked perfectly. Thanks again.

Hi Thomas,
The issue comes from Pylab not knowing how to deal with instances of
Sage's RealNumber class. When you do "4.0" from the command line, it
gets changed into "RealNumber('4.0')". You can see this with the
following commands:
sage: preparse('4.0')
"RealNumber('4.0')"
In order to get P
Hi folks,
Sorry to bombard the mailing list with questions, I'm starting to use
sage for more and more things lately. I'm trying to get a figure
together for a paper and thought I'd try using the bar() command in
pylab. However, the following code (modeled after an example in
matplotlib) gives an

Ok, that is good to know.

Sure, please let us know if you run into any more trouble.
Ok, I've downloaded the latest version (3.0.2) and compiled it
elsewhere than my home directory and it seems to work.
Thanks for the help.

A document at
http://modular.math.washington.edu/home/goreckc/sage/logic/bu/%3Cpropcalc.py%3E
describes how to use a module for propositional calculus. This involves
importing propcalc, boolformula, and logicparser.
In SAGE 3.0.2, when I try importing any of these three, the response is

Yes, that is what I meant. The 'dot' must have been invisible,
clearer to give the full path
Alright, I will do that then, might take me a couple of hours
though. ;)
As for the log: I have some webspace, so I'll upload it as soon as
it's compiled again. (I just deleted the sage directory and forgot,
that the install log was located there as well. ;) )

I think John was referring to /home/mozork/.sage/ (which is where some
SAGE stuff is
saved). I think he suggested deleting it and then starting SAGE.
Just in case there was a corrupted download, can you download sage-3.0.2, and
recompile? I just want to be sure that this is not a 32 bit ubuntu is
I0m not shore this was what you meant, but I've now moved sage to /usr/
bin/sage and I still get the same error.

Maybe there is some junk in your .sage directory. Try deleting (or
moving) it before running Sage.

Both these instructions are, in the respect that I used them,
completely the same.
All I practically did, was installing all the dependencies recommended
in the (apparently outdated) guide, downloading the tarball from

As for GAP, both commands seem to work fine:

Besides Georg's suggestion there is a file in
SAGEHOME/examples/calculus called field_plot2d.sage
which does some very crude DF plotting of 1st order ODEs.
(Designed specifically for teaching purposes.) You need to read it
into SAGE using the attach command, edg
sage: attach "SAGEHOME/examples/ca
I guess you mean hardy heron, ubuntu 8.04, 64bit?
Others are much better than I at deciphering the problem, but it vaguely
looks like you have a problem with the GAP install. Could you please
try
./sage -gp
and then quit SAGE, then try
./sage -gap
please?

Hi,
I've built sage (3.0.1) on my ubuntu 8.4 and the build worked just
fine. But whenever I want to use sage, I get an error for every
command I've tried so far.
e.g.
[EMAIL PROTECTED]:~/.sage$ ./sage

Dropped it, as I was having trouble with Virtual PC + XUbuntu. I
switched to VirtualBox. I have documented the problem I encountered
here:

You can use the plot_vector_field command:
# Declare your variables:
var('x t')
# Define you function, for instance:
def f(t,x):
return t*x
# Plot the associated vector field:
plot_vector_field((lambda t, x: 1, f(t,x)), (-1, 1), (-2, 2))
There seems to be something awry, however, compare

how can I plot the directional field of ordinary differential
equations?
x'=f(t,x)
