Hello,
I'd like to know if there is a way to define a variable in Sage as non-
commuting.
I am trying to multiply a few matrices together and take the trace,
*but* the matrix entries are non-commuting elements. So, I need Sage
to leave a term like a*x*a as-is and not change it to x*a^2.
This is
I have installed local Sage server.
I need some kind of workspace with multiple worksheets and common data
storage while working via web interface. What can you recommend in
this case?
I want to have a bunch of common files for different worksheets. But I
don't want to link them explicity to othe
how do I convert a differential expression from maxima to sage?
suppose i do
%maxima
depends(f,x)
eqn:'diff(f,x,1)
exit
now I am back to sage and I try
var('x')
f=function('f',x)
maxima('eqn').sage()
that doesn´t work of course. sage tells me "0"
How can I get a differential equation in sage
Hi,
I'm very sorry for the extremely late response. I'd just like to know if
you're still having a problem with this.

Dear Robert,
Thanks a lot for the suggestion. After typing in "ode_solve", the tab-
completion guided me to the class "ode_solver", which also works like
a charm. This is the reason for my late reply: I was so glad to get
everything working that I lost all track of time...
I know this is not th
Perhaps you have substituted unadverteadly some of the spkgs by previous
versions, I got this message before following exactly the recommendations given
in the Jaap Spies README instructions.

Hi Jaap,
No, I have no ETS installed yet.
