The ISET distribution includes a large number of scripts that illustrate how to use the code to simulate different aspects of scenes, optics, sensors, and displays.
The scripts are organized by general category
From the Matlab command window, you can find examples of scripts related to scenes by typing
s_scene<TAB> or t_scene<TAB>
Assuming ISET is on your path, this will tab-complete to the list of scripts that manipulate scenes.
Within the Matlab editor, you can select ISET functions and scripts to view and edit.
Videos that describe the theoretical basis and pragmatic use of ISET can be found at
