Problem with Anderson-darling test

Hello everyone,

I used a MATLAB FEX function namely AnDarksamtest, but after running the simple example as follows:

clear; clc;

X = [38.7 1;41.5 1;43.8 1;44.5 1;45.5 1;46.0 1;47.7 1;58.0 1;
 39.2 2;39.3 2;39.7 2;41.4 2;41.8 2;42.9 2;43.3 2;45.8 2;
 34.0 3;35.0 3;39.0 3;40.0 3;43.0 3;43.0 3;44.0 3;45.0 3; 
 34.0 4;34.8 4;34.8 4;35.4 4;37.2 4;37.8 4;41.2 4;42.8 4];

[AnDarksamtest, Pn] = AnDarksamtest(X);

I got this error:

Output argument "AnDarksamtest" (and possibly others) not assigned a value in
the execution with "AnDarksamtest" function.

It is worth mentioning that last year I used this code and its run perfect but now I get the error. Do you know how I can overcome this issue? Thank you all.

The function definiton is

function [AnDarksamtest] = AnDarksamtest(X,alpha)

which doesn't have but one return variable and you asked for two -- which it can't do.

Thank you so much. It fixed my problem; really appreciate you.
