Hello, Im quite new to Maxima and I want to use the atensor package to
do some clifford algebra calculations but it doesnt evalute certain
expressions. I started the demo and this is the output:
(%i1) demo(atensor);
batching #p/usr/share/maxima/5.13.0/share/tensor/atensor.dem
At the _ prompt, type ';' followed by enter to get next demo
(%i2) if get('atensor,'version)=false then load(atensor)
(%o2) /usr/share/maxima/5.13.0/share/tensor/atensor.mac_;
(%i3) ATENSOR can simplify noncommutative products in various
algebras._;
(%i4) Let us begin with a Clifford algebra_;
(%i5) init_atensor(clifford)
(%o5) done_;
(%i6) atensimp(u.u)
(%o6) sf(u,u)_;
(%i7) atensimp(u.v-v.u)
(%o7) 2*(u.v)-2*sf(u,v)_;
where I expected something like 1 and 2u.v . Seems like the sf(,) doesnt
get evaluated? Im using wxMaxima 0.7.1 and atensor v20041203.
Regards
