Turning a while loop into 1 line

Hi, for an assignment, I have to turn this while loop into one line

v=[4 11 22 5 33 -8 3 99 52];
newv_sol=[];
j=1;
i=1;
while j<=length(v)
    if v(j)<30
        newv_sol(i)=v(j);
        i=i+1;
    end
    j=j+1;
end
newv_sol

So far, I've only managed to make it in two lines with the find function and logical indexing.

x=find(v<30)
newv_sol=v(x)

Is there a way to combine these two?

Never mind, I seem to have figured it out.

newv_sol=v(find(v<30))

find is not required: logical indexing is more efficient:

newv_sol=v(v<30)

newv_sol=v(v<30)
