I have the function.
How do I write this in MATLAB?
I tried the below, but I don't think it is correct...
Vchain = 0;
for i = 1:N
Vchain = Vchain + 0.5*(D*(y(i)-y(i+1))^2 + (z(i)-z(i+1))^2) + g0*(m*z(i));
end

What is ‘D’?
In the image, ‘D’ looks like a function, not a constant. If it is a constant (as you have written it), the multiplication could be written outside the summation.

Try this :
Vchain = 0; for i = 1:N-1 Vchain = Vchain + 0.5*D*((y(i)-y(i+1))^2 + (z(i)-z(i+1))^2) + g0*(m*z(i)); end Vchain = Vchain + g0*(m*z(N));
