System Requirements

FOCUS currently supports Linux kernel 2.4 or above, Windows XP, Windows Vista, Windows 7, and Mac OS X.

At this time, we strongly recommend against using MATLAB R2008b on Unix-based systems. There are several unresolved issues with MATLAB R2008b that may prevent FOCUS from running.

Installation Instructions

Note to Windows users: Please make sure you have the appropriate Microsoft Visual C++ 2008 SP1 Redistributable Package (x86 or x64) installed for you computer, as these MEX files have been compiled using Visual Studio 2008.
