Folks, please let me know how to complete the sum of products in the "for loop" as shown below in order to get the correct answer. Thank you. HDaniel

clear all; % S=2i*3j; S1=0; S2=0; for i=0:1:2; for j=1:1:3; S1=2*i; S2=3*j; S=S1*S2; end end y=Sum(S)

Hi Hani,

A few tips first:

• When incrementing by one, you can simply do i=0:2, the increment value is only necessary if it is something other than 1
• You can simplify your code to do all the calculations on one line
• It is simpler to just add to S every loop iteration.

Doing as i suggest, the code looks as follows:

clear all; 
% S=2i*3j; 
S = 0;
for i=0:2 
    for j=1:3
        S= S + 2*i * 3*j; 
    end 
end 
y=S

k = (0:2)'*(1:3)*6;
S = sum(k(:));
