未定义函数或变量 'rndcheck'。
出错 gamrnd (line 38)
[errorcode rows columns] = rndcheck(4,2,a,b,m,n);
出错 sdm_mix>invgamrnd (line 432)
tempp = gamrnd(alpha,beta,n,m);
出错 sdm_mix (line 125)
sige(:,i) = invgamrnd( (length(y_use)/2 + a(i,1)), inv(resids+inv(b(i

@xixia33:
  1. What MATLAB version are you using?
  2. Have you made any changes to the MATLAB path?
  3. What shows up for this command?:
which -all gamrnd

the version is R2016a,I don't know if I have made any changes to the path.
when I use the invgamrnd.m,shows that:can't find the 'rndcheck' function.
what is the 'rndcheck' function? where to load it?
if I add this function to the path,there may be no such hint
