Background
To start EPHUS, one must invoke a startup file at the MATLAB command line. The file is a MATLAB function file (i.e., .m extension), located in the current directory or somewhere on the user's MATLAB path.
Every user/rig requires a customized startup file. The best way to create this file is to modify one of the supplied example files, which are constantly maintained on this site.
The startup files contain both configuration and application information. The vast majority of users only need to adjust the configuration information, which is in clearly demarcated sections of the startup file.
Some power-users may find occasion to modify the application information within the startup file. This will not generally be supported, but is relatively straightforward.
This guide steps through a typical startup file: gephus.m. For completeness, both the configuration and application sections are described. Most users should ignore the latter sections.
