Why am i getting complex number?

pos =zeros(num,2);

for j=1:num

pos(j,1)= 200*rand(1);

pos(j,2) = 200*rand(1);

end

I was trying to get positions and i am getting complex number in workspace. When i tried to display, it was real number. Why is workspace storing complex number?

What do you mean? You can run it here and see results.

num=3;
pos =zeros(num,2);
for j=1:num
    pos(j,1)= 200*rand(1);
    pos(j,2) = 200*rand(1);
end
pos

pos = 3×2

38.2616 166.3305 64.2819 142.4279 68.3623 17.7350

Are you sure you got complex numbers? Complex numbers are like below.

clear i j;
i

ans = 0.0000 + 1.0000i

j

ans = 0.0000 + 1.0000i

a=2+3i

a = 2.0000 + 3.0000i

b=4-5j

b = 4.0000 - 5.0000i
