@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

[xixia33]

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
