Take advantage of MATLAB’s vectorisation capability —

N = 10;
ff = (1:N) ./ cumprod(1:N)

ff = 1×25

1.0000 1.0000 0.5000 0.1667 0.0417 0.0083 0.0014 0.0002 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000 0.0000

ffsum = sum(ff)

ffsum = 2.7183

Make appropriate changes to get different results.
