Question

Write a for loop that is equivalent to the Matlab defined function sum(A), where A is a matrix.

%this is what i got feel free to completely change if need to

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

%having trouble with the next line keep getting error

%expression cannot be assigned to multiple values
[rows , cols] = size(A);
total = 0;
for i=1:rows
for j=1:cols
total=total+A(i,j);
end
end
disp(total);

Answer 1

A = [1 2 3;4 5 6;7 8 9];
[rows,cols]=size(A);
result=[];
for j=1:cols
    total = 0;
    for i=1:rows
        total=total+A(i,j);
    end
    result(j)=total;
end
disp(result);
