Question

consider the following MATLAB code. What elements of x will be summed up.

x= [3 4 5 6 7; 1 2 4 6 8; 5 7 9 1 3; 8 7 6 5 4; 9 8 7 6 5]

total=0                                                                                                                                                                                                     for n=2:2:4               

        for k = 1:1:3

                   total = total + x(k,n)

       end

end

second question: how would i be able to test this myself? Would I use the command window of MATLAB or the editor?

Explanation / Answer

1. value of x which will be summed : 4, 2, 7, 6 , 6 , 1

2. you have to print the value of x(k,n) which will be added with total. I have bold that code in code, check it

that will print value of x every time before added with total.

x= [3 4 5 6 7; 1 2 4 6 8; 5 7 9 1 3; 8 7 6 5 4; 9 8 7 6 5];
total=0;
for n=2:2:4   
for k=1:1:3
x(k,n)
total=total + x(k,n);
end
end
