Summation with FOR loop question

I am fairly new to MATLAB. How do you get an answer for this using a FOR loop?

Answer 1

[Mark Sherstan]

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

Oliver - since this is most likely homework and I'm assuming that you have been instructed to use a for loop, see for loop to repeat specified number of times and factorial. An alternative to using a loop is vecorization..see using vectorization for more details.

format long
fak = 1.0;
s = fak;
for i = 1:1600
  fak = fak/i;
  s = s + fak;
end  
s
exp(1)
