I am trying to evaluate an objective function and trying to figure out how to translate this into Matlab form.

I know I have to do a loop somewhere but just can't figure out how to start. Any guidance would be really really appreciated.

Essentially k = 1: 5 and j = 1:J and n = 1:N

Where does Pj fit into the equation?

Thank you for the question. You can ignore the Pj.

abs(Gkj - sum(f(c(1:N)) .* gkj(X(1:N))))

provided that f and gkj are vectorized functions.

If they are not, then

fv = @(C) arrayfun(@f, C);
gkjv = @(C) arrayfun(@gkj,C);
abs(Gkj - sum(fv(c(1:N)) .* gkjv(X(1:N))))
