MATLAB: How to convert this for if loop into a while loop

forloopMATLABwhile

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

Best Answer

 x=6*rand(1,10)+2
 i = 1;
 while i<11
    if i<5
        x(i)=-1;
    elseif i>=5 && i<8
        x(i)=1;
    else
        x(i)=3;
    end
 i = i+1;
 end

Should do the trick, just don't forget to update you i .
