Please take the time to fully understand what is going on but this should get you started.
f = 0; % Set the initial conditions
for ii = 0:1600 % Looping from 0 to 1600 as denoted in the summation
f = f + 1/factorial(ii); % Add the previous response to the new response (hence summation)
end
fprintf("The answer is %0.3f\n",f) % Display the answer to 3 decimal places
