Hi William,
Try putting import sage.matrix.matrix as the line *right* before
you use sage.matrix.matrix.is_Matrix(). I.e., do the import in the
function, not at the module level.
That is what I first tried. That results in the same error. I added
the line

Hallo,
I'm new to sage and tried to use it. After the installation I started
a worksheet and tried the following
circle((0,0), 1, rgbcolor=(1,1,0))
and got the replay
/Applications/sage/local/bin/sage-sage: line 349: 4119 Abort

What is wrong?
I guess you are using a mac, but can you tell us what version the OS is and
what version of Sage you are running? Is it a binary, for example?
(This might help others on the list diagnose the problem.)

Thanks for your answer, yes, I do use a mac
OS X 10.6 (snow leopard)
and the Sage version is
sage-4.1.1-OSX10.5-intel-64bit
Sage has no problem with (simple) calculation, I already tried that
and it works fine.

Thanks for the answer, well, I violated a basic rule: Don't use new
systems too early. I will wait for the upgrade and hopefully it won't
take too long. I'm specifically intersted in using Sagetex but it
won't work without Sage.

This problem was just reported again on sage-support. To those who
reported it (Gary, Jeannine), did you use the 64-bit binary? That was
the one which caused the problem on the most recent report. Does the
32-bit binary work properly for you? (The error messages above all
say it's looking for
This is a really nasty bug.. Symbolic maxima and minima are
mathematical standard tools, they should at least be _callable_ in
standard sage. One can see the problem this way:
p = var(p)
show( plot(max(p,3),(p,0,10)) )
show( plot(min(p,3),(p,0,10)) )
Could someone please post a quickhack to
Now how do I evaluate f itself at those same points. I can't seem to

Hi Burcin,
Many thanks for theses details about sage. I try to understand what you
prefer, and why.
The main reason I left this simplification exp(a)^2 to exp(2*a) while
fixing #6948 was that MMA does things this way.
All right : MMA is good.
Another consideration was that before

f is a vector-valued function. Right now, I think the best way to
evaluate a vector-valued function is to declare it a vector:
f = vector([f1(x1,x2,x3), f2(x1,x2,x3), f3(x1,x2,x3)])
We are
