leave_early = false;
for j=1:i
  if leave_early; break; end
    for k=1:L
        if map(j,1)==mat(k,2)
                mat(k,2)=map(j,2);
                leave_early = true;
                break
        end
    end
end

[i1,j1] = find(bsxfun(@eq,map(:,1)',mat(:,2)),1,'first');

mat(i1,2)=map(j1,2);
