So ima trying to get a matrix from a nested loop but i keep getting a one answer SIGMA in the workspace but thanks to the disp(SIGMA) i get a bunch of numbers in the command window. Why are they different?

for x=0:30
    for y=0:30
        SIGMA=(x*y);
    end 
end

place disp(SIGMA) between ends

Change

          SIGMA=(x*y);

to

          SIGMA(x+1,y+1) = (x*y);
