Unzip the files from the file FRIT_ToolBox.zip. It creates a folder named "FRIT_ToolBox_x_x_x". Add this directory and its subfolders to the Matlab search path (File menu/Seth Path...-->Add with Subfolders).

The individual FRI methods can be reached as functions that can be invoked with proper parameters. However, there are two easy-to-use GUI programs that help you to try the methods. They can be started by the command

>>FRIT

and

>>TestIt

in the Matlab Command Window. Enjoy the program.
