MATLAB: How to manipulate the output of a for loop to get the sum of the output data set

for loopsum

Please i need hint on how to manipulate the output from a for loop do summation of differences between it and a data set. An example is shown below. I tried it but it only computed for the first for loop neglecting the other data set.
for f = [1 4  8  10];
 b=2;
 c=1;
 d=1;
 n=4;
 N= f*b*c*d
 M=[4.5  10  20  25];
 Y = (M-N)/M;
 Z=(100/n);
 A =(sum(Y)*Z);
end
disp(A)

Segun, are you trying to compute the cumulative sum?
 A = 0;
 for f = [1 4 8 10] 
    b = 2; c = 1; d = 1; n = 4; 
    N = f*b*c*d; 
    M = [4.5 10 20 25];
    Y = (M-N)/M; 
    Z = 100/n; 
    A = A + sum(Y)*Z;
 end
 disp(A)
