下面是我的代码，但总提示维度不一致，望大神指点一二，非常感谢啦
" t; i  H: Y% q# Y/ k3 x0 xfunction ave_dpoint=ave_dispoint(p)
0 }0 J' \: b2 Nk=8;
  q# V/ S: }0 a2 }( [p_Mdl=KDTreeSearcher(transpose(p));
7 E/ w! _/ A# q9 l( g' ^p_neighbors = transpose(knnsearch(p_Mdl, transpose(p), 'k', k+1));
m=size(p,2);
( Z: y% J0 j- P( e' F# N) o2 ]for i=1:m
4 {, g: s; r) k0 U* Tx = p(:,p_neighbors(2:end, i));
$ n, C2 `! F" Q, _2 xy=sqrt((p(:,i)-x(:,i)).^2);
9 |, `7 o! ^; {) W% Tend
ave_dpoint=mean(y);
end
( h* S+ n$ S" c5 K

relchhiclty
