Converts a k-tensor to alternating form

S |
A multilinear form, an object of class |
Given a k-tensor T, we have

Thus for example if k=3:

and it is reasonably easy to see that Alt(T) is alternating, in the sense that

Function Alt()
takes and returns an object of class
ktensor
.
Returns an alternating k-tensor. To coerce to a k-form,
which is a much more efficient representation,
use as.kform()
.
