Hello. MATLAB beginner here. I'm trying to convert a for loop to a while loop to finish up a final homework problem and it's supposed to get the same results, but it's not. I'm only getting the random numbers from the beginning equation. I believe the issue shouldn't be this hard to find, but I can't pinpoint what's wrong.

x=6*rand(1,10)+2
for i=1:10
    if i<5
        x(i)=-1;
    elseif i>=5 && i<8
        x(i)=1;
    else
        x(i)=3;
    end
end
x
