Hi,
I am trying to plot the solutions the following system of ODEs
var('t')
A = function('A',t)
B = function('B',t)
de1 = diff(A,t) == -k1*A+k2*B
de2 = diff(B,t) == k1*A-k2*B
sol = desolve_system([de1,de2],[A,B],ics=[500,0])
show(sol)
solA, solB = sol[0].rhs(), sol[1].rhs()
plot((solA,solB),(t,0,
Good news, but I just checked PyPI (via easy_install) and it is still
pointing to version 0.28 of openopt. Please upload the latest
versions.

After installing sage 4.3.3, the cell evaluation hangs indefinetly if
I combine %cython and %timeit modes.
if I remove the %timeit the cell executes normally.
anyone else can confirm this behavior?

Hi,
I really liked the method for speeding numerical integration of ODES
presented in the sage documentation. However, it uses the GSL solver
instead of the scipy.integrate.odeint I normally use.
I tried to apply the same methodology but I can't get past this error:

randstate.pyx didn't mention explicitly that the RNG from libc is of
poor quality and to be avoided. Moreover, by using the RNG built into
Python, I guarantee reproducibility across platforms (I think) and
avoid external dependencies...

Hi, I have just upgraded to 4.2 and I am having problem with LaTeX

Answering my own question:
I can share only the worksheet.txt from within the .sws package.
Should there be a way to export only the source code? Maybe also as
a .tex file (sagetex enabled?)
thanks,

When exporting a worksheet, is there a way the exclude files from the
DATA directory from the packaging, in order to reduce the
resulting .sws file size? Naturally I could go to the data directory
and delete them by hand before exporting, but it is a bit of a hassle.

is there an equivalent to:

which can be run from within Sage?

I did not know about the DATA variable.
It seems, however, that I must explicitly dump the pickles into DATA,
otherwise they end up in another directory.

I wonder if it would be possible, when in python mode: "%python", Sage
would revert to use standard python (and numpy) types.
I can now replicate my previous bug report with just a line of python
(excluding the import):
%python
from scipy import stats
stats.randint(0,23).ppf(3)
I don't see why
Thanks!

So it seems that there is no (easy or otherwise) way to build from
latest development tree, only from the last "stable" source tarball.
That's what I was hoping for.

I had already bumped against this type compatibility

preparser(False)
However, this error won't go away when the preparser is turned off.
