Hi
Any clues what is happening here? I am trying out calculations as Yann
mentioned.
M=matrix(SR,3,[1,1,1,x^a,x^b,1,y^a,y^b,1])
M.det()
(y^b - 1)*x^a - (x^b - 1)*y^a + x^b - y^b
Now if I try the one below
M=matrix(SR,4,[1,1,1,1,x^a,x^b,x^c,1,y^a,y^b,y^c,1,z^a,z^b,z^c,1])
M.det() gives
Traceb
Hi
Thanks for the suggestions. But there is one issue which still
rankles. Maybe it's just me, but I would prefer
x^a*x^b-x^c*x^d to turn up as x^(a+b)-x^(c+d)
Anyway, thanks again for the help

Thanks.
No problem. I wrote a function to create what I wanted using
'polygon'. It is useful to know that colormaps were not the answer.

Sounds good. Thanks again for all your help.

Is there any way to limit the display range of a 3d plot,
using either jmol or tachyon? (Something similar to xmax
and ymax with a 2d plot.)

My program just needs the following as far as I can tell:
fft and fftshift,
auto-correlation
svd
matrix manipulation
basic calculus
complex numbers
I'm trying to create a gui to reconstruct an image from its fourier
moduli from data taken via usb.
Do you think it is possible with the packages av
I am using Sage Version 4.3, Release Date: 2009-12-24. The two plots:
matrix_plot(matrix(2,[2,2,3,3]),axes=false,frame=false)
matrix_plot(matrix(2,[1,1,3,3]),axes=false,frame=false)
look the same to me. I tried various cmaps with the same result. Is
there a way to set a cmap so that the plots

It depends entirely on the packages and the program. If your program
does nothing but say "2+2
That's discouraging. I can still use a lot of the packages that sage
comes with to create the program in python and then compile to exe,
right?
Thanks for your quick response.

Sage is an extremely complicated program involving over 5 million
lines of code and multiple running processes and programs that have to
be run in
I don't undestand why not though. If it is possible to do this python,
then why not with sage?

This is absolu
I am running Sage on vmware. I'm wondering if I can make a piece of my
program with sage and then turn that into a python script and then
cross-compile it to run as a windows exe that people without Sage or
Python can use.

Technically, I think yes - but that would not do anything useful at
all. I suggest
Is it possible to make a script on sage, import its libraries into a
python script and then compile that script as a standalone windows exe
using py2exe or pyinstaller?

Hi,
In the same context, how can I get the following to work?
A = matrix(SR, [[x, 1], [x**3, 4]])
A.eigenvectors_right()
__main__:1: UserWarning: Using generic algorithm for an inexact ring,
which may result in garbage from numerical precision issues.

Nice example, Yann.

To Vasu: Notice that it's important that x is a symbolic variable
here, not a polynomial indeterminate.

Hi
I wanted to know how could one compute symbolic determinants. To give
an idea of what I am looking for,
R.=PolynomialRing(QQ,'x')
M = [ x^a,x^b][x^c x^d]
I would like to compute the determinant of the 2*2 matrix M, say. Now,
I know that a,b,c,d are all integers but I don't want to give them

Roland,
Thanks for the suggestion; I'll go the VMplayer route. It's too bad,
really. I try to use FOSS whenever possible. Any idea what causes
this problem?
