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
6 m4 X6 i1 d, x2 Q% \8 i. Mfunction ave_dpoint=ave_dispoint(p)
k=8;
1 i5 e9 V+ o) `5 |6 R2 t$ `p_Mdl=KDTreeSearcher(transpose(p));
) z' v3 a- r, Up_neighbors = transpose(knnsearch(p_Mdl, transpose(p), 'k', k+1));
m=size(p,2);
for i=1:m
' l5 r8 s! a' Bx = p(:,p_neighbors(2:end, i));
  m6 {4 d4 ]% O, zy=sqrt((p(:,i)-x(:,i)).^2);
