I am new at MatLab, so it would be much appreciated if you could keep it somewhat simple. So, I have a formula that relates two variables, let's say y = sin (x). How could I create a vector X that "holds" discrete values of x, let's say X = [1 2 3 4 ... ], and then apply this vector in the formula sin (x) and get a vector Y that "holds" discrete values of Y; in this example Y = [ sin (1) sin (2) sin (3) sin (4) ...]?

Basic MATLAB concepts, such as how to define vectors of values and call functions on them, are explained in the introductory tutorials (which are highly recommended for all beginners):
