大家好，我是用LeSage的空间计量工具包Jplv7里的anselin的那个例子的时候,就是原原本本，什么都没变但是一运行就出现了这个Undefined function 'make_neighborsw' for input arguments of type 'double'.
Error in sdm_d (line 26)
W = make_neighborsw(latt,long,6);

是我下的东西原本就有问题吗？
这是代码：
n = length(anselin);
y = anselin(:,1);
x = [ones(n,1) anselin(:,2:3)];
latt = anselin(:,4);
long = anselin(:,5);
vnames = strvcat('crime','constant','income','hvalue');


W = make_neighborsw(latt,long,6);
Undefined function 'make_neighborsw' for input arguments of type 'double'.
Error in sdm_d (line 26)

W = make_neighborsw(latt,long,6);

info.lflag = 0;
info.rmin = -1;
info.rmax = 1;
results = sdm(y,x,W,info);
prt(results,vnames);




prior.lflag = 0;
prior.novi = 1;
ndraw = 2500;
nomit = 500;


results2 = sdm_g(y,x,W,ndraw,nomit,prior);
prt(results2,vnames);




out =  [results.bstd results2.beta_std results.bstd - results2.beta_std
        results.pstd results2.rho_std  results.pstd - results2.rho_std];
   
in.cnames = strvcat('Hessian estimates','MCMC estimates','Difference');
rnames = strvcat('Std dev');
vnamesx = strvcat('constant','income','hvalue','W*income','W*hvalue');
in.rnames = strvcat(rnames,vnamesx,'rho');
in.fmt = '%16.8f';


mprint(out,in);





麻烦哪位好心人指点一下，谢谢
