最近空间计量学的太辛苦了，跑demo程序出现了无数bug,解决了一个又来一个了！向大家请教下！
在运行demopanelscompare中，这次出错的试panel_effects_sar，报错如下：
??? Error: File: panel_effects_sar.m Line: 30 Column: 3
Expression or statement is incorrect--possibly unbalanced (, {, or [.


Error in ==> demopanelscompare at 65
panel_effects_sar(results,vnames,W);


检视panel_effects_sar:报错程序为红色字体。
function panel_effects_sar(results,vnames,W)
% PURPOSE: computes and prints direct, indirect and total effects estimates
% for Elhorst SAR spatial panel models using the LeSage and Pace code
%---------------------------------------------------
% USAGE: panel_effects_sar(results,vnames,W)
% Where: results = a structure returned by a spatial panel regression
% vnames = a structure of variable names
% W = spatial weights matrix used to estimate model
ndraw=1000;
uiter=50;
maxorderu=100;
nobs = results.N;
[~, nvar] = size(results.xwith);
rv=randn(nobs,uiter);
tracew=zeros(maxorderu,1);
wjjju=rv;
for jjj=1:maxorderu
wjjju=W*wjjju;
tracew(jjj)=mean(mean(rv.*wjjju));

end



这是Elhorst的程序，我之后调用另一个程序包里的panel_effects_sar发现出错的这一行程序是这样写的，两者不一样：
ndraw=1000;
uiter=50;
maxorderu=100;
nobs = results.N;
[junk nvar] = size(results.xwith);
rv=randn(nobs,uiter);
tracew=zeros(maxorderu,1);
wjjju=rv;
for jjj=1:maxorderu
wjjju=W*wjjju;
tracew(jjj)=mean(mean(rv.*wjjju));

end


也就是[~. nvar]变成了[junk nvar]
在运行demopanelscompare时，有一个direct_indirect_effects_estimates.m的程序中红色行报错：
N=results.N;
parm=results.parm;
cflag=results.cflag;
if (spat_model==0)
[~.nvar]=size(results.xwith);


同样我改成[junk nvar]=size(results.xwith),就成功了。
但是这次用在panel_effects_sar,就不行了！

就高手帮助呀！
