问如何在MATLAB中找出两个不同向量的连续数列？

x = [-2 -2 -1 -1 -1 -2 -1 0 5 -1 0 5 -1 0];
y = [ 2 3 4 5 -1 0 5 -1 0 5 -1];
for n = min(numel(x), numel(y)):-1:1; % try sizes in decreasing order
    x_sliding = reshape(im2col(x,[1 n],'sliding'),n,[]).'; % reshape needed for n=1
    y_sliding = reshape(im2col(y,[1 n],'sliding'),n,[]).'; % reshape needed for n=1
    [ind_x, ind_y] = find(pdist2(x_sliding, y_sliding) == 0);
    if ~isempty(ind_x)
        ix_start = ind_x;
        iy_start = ind_y;
        ix_end = ind_x+n-1;
        iy_end = ind_y+n-1;
        break
    end
