Hi,
There are some people in the list who would like to use itensor.
Well, it's currently broken, some functions, like components(), canten()
and probably some others, don't work. However it still can be used.
I have some patches and demonstration file showing the current abilities
of "itensor", and some screenshoots as well.
The proposed patches could be considered as purely cosmetic. They correct files in
correspondence with common lisp syntax. Like (in-package 'maxima)
is replaced by (in-package "MAXIMA"), and (MAPCAR 'LAMBDA(
is replaced by (MAPCAR #'LAMBDA( .
Note, that cool feature provided by generate(eqs) does work.
It gives the possibility to use results obtained by "itensor" in
"ctensr". In that demo I demonstrate the derivation of the diffusion
heat transport equation in cartesian and spherical coordinates.
For a moment I have no public place where to put this staff.
So you can ask me directly or if somebody have a place I would put it there.
All the best,
Valerij.
