Please don't post pictures of code. We can't copy and paste pictures into MATLAB and run it. Instead, copy your code as text, highlight it, and then press the CODE button to format it.

Well, tau is only two elements and w is a lot more than that, so you can't multiply them element-wise like you are attempting to do. Maybe you wanted to use tau(t) inside your for-loop instead of tau? And for plotting, maybe just x instead of x(w)?
