another poster / vect.mac



I couldn't reproduce the desired equation using the (patched) vect.mac. 
However I don't know ANYTHING about this stuff...

Can maxima do this with vector field entities?

For example, if u and v are vector fields, how will maxima handle

curl(v cross u)

if it can return something like

u*div(v)-v*div(u)+(v dot del)u-(u dot del)v

and similar expressions for

divergence(v cross u)
grad(v dot u)

I would jump to it in a heartbeat...
