Fill up a variable number of rows to match a certain size

Hi,

I'm running a code of image analysis in which I get a matrix called "Results" that is suposed to be 200x1. Sometimes, instead of 200x1, the Results matrix is smaller, such as 191x1, or 194x1, depending on the original image.

I'd like to concatenate all the Results matrices from every image in one matrix called ResultsGathered, but since they have different sizes, Matlab does not allow me.

How can I make the code to fill up automatically the shorter matrices with 0 to match 200x1?

Thank you

Results = rand(194,1); % a random 194-by-1 vector

disp(Results(end-1:end)); % show the last two elements

    0.9591
    0.8868

% extend with zeros to length 200 if it's smaller than 200
if size(Results,1) < 200
    Results(200,1) = 0;
end

disp(Results(end-7:end)); % show the last 8 elements

    0.9591
    0.8868
         0
         0
         0
         0
         0
         0
