Hi,
I was wondering if there is a way to return only the subscript of an element in a sequence.
Essentially I have something like t:=a[[1,2]] and I want the list [1,2] to be returned. I can't think of anyway to do this. For instance solve(t=a_x,x)...
Any help would be appreciated.
op does the job
Essentially I have something like t:=a[[1,2]] and I want the list [1,2] to be returned.
This could be obtained through op(t), but I doubt it will help with the solve question.
