MATLAB: How to build a vector with dynamic variables

dynamic variableloop

I have variables :
q1 = 10;
q2 = 20;
q3 = 3;
q4 = 4;
q5 = 55;
...
qN = x;
and I want to put them in a vector Q that i created like :
Q = zeros(N,1);
How can I insert each variable in the vector at the correspondig place with a loop. Something like that :
for i = 1:N
    Q(i)= % here qi
end

I hope you're doing this because you have now realized that it was a bad idea to create q1...qN to begin with and are seeking to undo the damage.
>> Q=arrayfun(@(i) evalin('caller',['q' num2str(i) ';']) , 1:5)
Q =
    10    20     3     4    55
