# How to store the output of a function?

I used a function from FEX, when it's run the output is showing in the command window but nothing adds to workspace. Is any way exist to store "Probability associated to the Anderson-Darling rank statistic" (p-value) which shows in the command window?
Here is an example:
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(X)
Thanks

I would run the file in debug mode and step through it until you find the section that produces this text. Somehwere in that section is a variable that contains p-value. If it's not already included in the outputs, you could add it.

You can modify the function to output Pn
function [AnDarksamtest, Pn] = AnDarksamtest(X,alpha)
The function itself is well-documented !
...
fprintf('Standardized Anderson-Darling rank statistic: %3.7f\n', ADKsn);
fprintf('Probability associated to the Anderson-Darling rank statistic = %3.7f\n', Pn);
disp(' ')
fprintf('With a given significance = %3.3f\n', alpha);
