I would like to compute the composition (f o g) where f, g are
polynomial maps from R^2 to R^2. For example, if f(x,y) = (y, y^2 +
x), I would like to obtain
(f o f)(x,y) = (y^2 + x, (y^2 + x)^2 + y)
In Maple the code is more or less :
f := (x,y) - (y, y^2 + x);
(f...@f)(x,y);
Is there a way to
Hi,
I'm trying to build a fortran extension module with f2py using and spkg I've
built for sage 4.4.2 on Mac OS X 10.6. When I just run 'python setup.py
install' from the commandline (with SAGE_LOCAL at the front of my path,
etc.) The module build/installs fine, but when in installing as an spkg
Hi together, I'm trying to install pyhdf to work with NASA's HDF-EOS
files. Unfortunately it does not work, if I follow these instructions:
http://pysclint.sourceforge.net/pyhdf/install.html
So I compiled szlib and hdf4 succesfully and did in the sage shell (I
have sage 4.3.3 and Suse 11.1):

Hello,
I am new to this list, and relatively new to Sage. I'm puzzled by the logic
of one part of Sage though.
Although I don't have access to Mathematica at the minute on this computer,
I know if I compute the first zero, I get something like
In[1] = ZetaZero[1] //N (to get a numerical value)

Did you read the documentation of the function? It makes it quite
clear:
Definition: lcalc.zeros(self, n, L='')
Docstring:
Return the imaginary parts of the first n nontrivial zeros of
the
L-function in the upper half plane, as 32-bit reals.

hello Jason,
This doesn't work either... :(
matlab doesn't even start with xvfb-run command.
it gives lot of errors.

So do NumPy arrays not display like a matrix in the notebook?
That's correct, at least for show. You could convert

As William pointed out, is the original problem resolved by one of the
other messages? If not, can you precisely state the problem as it now
Yes, matlab does save the images properly to the directory. But the
problem here is to get the image displayed on the web browser itself.
Thanks,

Hi Chris,
Are you on a 64-bit mac, i.e. core 2 duo or newer? I believe Sage's
implementation of f2py is broken on 64-bit macs - certainly it is
broken on mine too.
There is a simple patch that fixes this problem at
http://trac.sagemath.org/sage_trac/ticket/8010 , if anyone wants to
review it.
Hey, thanks, that patch fixed it. Yes, I'm on a 64-bit mac. We've had a lot
of trouble with numpy distutils and fortran on the mac unrelated to sage. I
was hoping that sage would provide a way to avoid those hassles among other
things. Apple could make life a hell of a lot easier by including
