[Axiom-developer] Playing with Axiom

[Bob McElrath]

I started playing a bit with Axiom,

(Any comments on the above page are welcome)

Can anyone answer for me:

 1) How do I unassign/undeclare a variable?  i.e. 
    a: Matrix(Integer) := diagonalMatrix([1,1])
    a: Integer

 2) The subst() operator doesn't work on my tensors.  Is there a better
    way to substitute/evaluate when you're substituting into a complex
    object?

 3) Let's say I wanted to allow the conversion of rank 0 tensors into
    their scalar counterpart.  Any idea where to start?
