2 3 5 1 6 0 0 3 4 7 2 0 6 2 
  convert in : 
2 3 5 1 6 3 3 3 4 7 2 6 6 2    

rule: I start from the bottom and look for zeros... I assign each zero equal to the NonzeroPrevious value

Assuming the last element is not zero -

in = [0 2 3 5 1 6 0 0 3 4 7 2 0 6 2].';
idx = in==0;
while any(idx)
    in(idx) = in([false; idx(1:end-1)]);
    idx = in==0;
end
disp(in)
