forward and backward value

Hi, Im begining with Matlab. I have a list of 20 values and my equation is x=sin(w2)-sin(w1), w2 is the forward value and w1 is the backward, how to do this?

We don't know what you mean by forward value, and backward value. Jargon that you make up is known and understood only by you.

So, how to do what?

[Steven Lord]

Let's say your list of values was stored in a variable w:

w = 1:6

What exactly would you expect x to be and how would you compute that (with pencil and paper / marker and whiteboard / stick and sandbox / etc.)?

I also don't know what you want. Let's say you havfe 20 w2 values and 20 w1 values in two arrays. Now, how to do what? You already have an equation for x, which is probably also a 20 element array. Do you just want to plot it, like

plot(x);
