If x is your series.
N = length(x) ;
FI = sum(abs(diff(x)))/N ;

I guess you figured it out since you accepted the answer (remove the division by N), but here is the answer assuming N is the length of the x vector:
FI = sum(abs(diff(x)));
or more accurately, assuming we just want to sum up to N and we have no idea how many elements are in x (might be N or might be something else):
FI = sum(abs(diff(x(1:N))))
