A small interactive program for learning about Control Charts (Shewhart, CUMSUM). The program is an educational tool, that has been made freely available. It is maintained as needed (bug fixing), but if additional functionality is desired contact the contributers of this git repository.
The app runs in MATLAB either locally hosted or through MATLAB online. A small user guide is available below. Note, the program is can be made available as a standalone application using the MATLAB compiler to produce an *.exe file
