The thing is, it IS an assignment that's going on. In the case of a range, especially, "for i=1:5" says "loop 5 times, with i=1, then i=2, then i=3, then i=4, then i=5". "i' is being assigned to on each iteration. Think of it this way - suppose you were using elementwise operations. You could write
i=1:5 A[i]=B[i].*C[i] or, you could write it as a loop... for i=1:5 A[i]=B[i]*C[i] end The two pieces of code are doing exactly the same thing; one is just explicitly writing the loop. In what way does restricting to "in" help, in this situation?
