Freeing Up System Resources on Windows Systems
There are no functions implemented to manipulate the way MATLAB handles
Microsoft Windows system resources. Windows uses system resources to
track fonts, windows, and screen objects. Resources can be depleted by using
multiple figure windows, multiple fonts, or several UI controls. One way
to free up system resources is to close all inactive windows. Windows icons
still use resources.
Reloading Variables on UNIX Systems
On UNIX systems, MATLAB does not return memory to the operating
system even after variables have been cleared. This is due to the manner in
which UNIX manages memory. UNIX does not accept memory back from a
program until the program has terminated. So, the amount of memory used
in a MATLAB session is not returned to the operating system until you exit
MATLAB.
