Suppose I have a vector 'v' created by use of the 'ApplyMatrix' command.


How do I extract its first, or last, or 2nd if a vector in 3d, element?


I tried First(v) and Last(v) and also Element(v,1) and nothing works.


Thanks!

Try this x(v), y(v), z(v).

also (0,1,0) v

in some cases better for formulas
