I understand how to set it up in a matrix form on paper but I'm new to Matlab and I have to use Matlab to compute it. Thanks

This is a least square fit problem. I know V = (A*T*A)^-1 A*T*Z. I need help with doing this on Matlab. You wrote V = A/Z. That does not do anything sir

No, I wrote v=A\z. It will do exactly what you request.
