Hello!
I have been on the search for MATLAB code which estimates the parameters for the General Normal Distribution (version 1 & 2) with confidence intervals for each of the parameters.
I have searched for a viable solution for some time but have not found any.
Any help would be greatly appreciated!
Thank you!

Did you try fitdist() in the Statistics and Machine Learning Toolbox? Or simply mean() and var()?

I did look at fitdist() in the 2015b version but with no luck. I have followed the same approach for multiple distributions (this one is one of the last I am looking for) but to no avail.

Why not? What went wrong? It's pretty simple. How about just doing
theMean = mean(yourData(:));
theVar = var(yourData(:));
That defines the Gaussian parameters. What more do you need?

That is not quite what you need for the general version. See link: https://en.wikipedia.org/wiki/Generalized_normal_distribution
