The Gauss Hypergeom function pfq works pretty fast , compared with the one of MATLAB. But the performance may not be satisfactory, especially when integration is involved.

With time, and some improvements, this could be a File Exchange treasure. Here is some good documentation on how to share data between workspaces, creating guis, program development.

I think Robert Howrd is being a bit harsh. This package definitely does not deserve 2 stars.

It is obviously the culmination of many years of work by the author and as such deserves much respect. So, I'm ok with having given one more rating of 5 stars to balance his 2 stars.

On the other hand, this could be an exceptionally excellent package, and it is unfortunately restricted from being so by some sub-par programming techniques, as mentioned above. So the overall rank should just be average right now.

I'd like to see less use of global variables in your programming of the GUI. It's very difficult to sort through what is causing the problems due to these. Also, I'm not sure, but I think it is generally frowned upon in application programming. It consumes more memory than needed at any given time.

Also, it appears that your reliance on xlsread is causing problems. xlsRead will call the excel server as part of it's internal program. However, not everyone has excel. In fact, I prefer to use the open source office suite called LibreOffice.

Could use some basic improvements.
1) Prepend package files to prevent naming conflicts
2) Update help documentation to reflect Matlab standards
3) GUI does seem to have some problems. A readme file would help guide the user.
Otherwise, an impressive collection.
