how to compare 2 vectors with same size , but columns is not always the same

foreach element if a> b, set to 1;if a<=b ,0

if true
training = rand(rownum,n);
origpoint= [a1,a2];
  for i = 1:rownum
  for j = 1:n
      if training(i,j)<= origpoint(j)
          Qzone(i,j)=0;
      else
          Qzone(i,j)=1;
      end
  end
end
end
my problem is origpoint may have 4 or more elements, so 2 loops may not make it ,
like when origpoint =[a1 ,a2,a3],it needs 3 loops, training an origpoint have the same columns;but if more an , how to figure out

We need an illustration of what you want to start with and what you want as a result. It’s not clear.

i got it ,

if true
  training = rand(rownum,n);
origpoint= [a1,a2,...,an];
for i = 1:rownum
    Qzone(i,:)=training(i,:)<= origpoint(:);

end
end
