File Information

Description

This task manager like tool displays real time memory state of MATLAB, HG, and Java using time based strip charts.

The following information is displayed:
* Memory allocated by MATLAB
* Memory allocated by Java
* Memory allocted by the O/S
* Number of MFiles in MATLAB memory
* Size of m-file parsing stack

To see real time MATLAB memory allocation, start MATLAB with the O/S environment flag "MATLAB_MEM_MGR" set to a "debug" as in: set MATLAB_MEM_MGR = debug.

Example:

>> monitormatlab
>> bench
See the following link for more information on using O/S Memory to help with large data sets:

25 May 2005	Elmar Tarajan	Nice idea - thanks you!
14 Jun 2005	gorden jemwa	A very useful tool, especially on WIN XP, which has poor RAM management capabilities!
08 Feb 2006	Tarzan Good	Very useful! Nice to know when to use >>clear all :-)
14 Feb 2006	Cary Martin	Useful application for diagnosing memory management problems, including for the toolbox functions. Note that under Windows XP you can easily set the required OS flag via Control Panel --> System --> Advanced --> Environment Variables --> New This is much easier than mucking around at the command prompt.
04 Jul 2006	Ofek Shilon	I had trouble running GUI-apps after running monitormatlab, and here's why: At the function localShutDown, add the line - ' localSetHGCreateFcn([]); ' (undo some GUI defaults changes). Other than that - nice and useful utility. Thanks!
03 Jan 2007	Paijit K	Well done. Thanks for all

14 Jun 2007	Shlomi Galperin	BEWARE: SEVER WARNING!!! This utility will mess up with your personal code (the "fig" files) and also with your windows registry. After installing it' it is impossible get rid ot it, and you must include it in your path or project, otherwise you will suffer from run-time warnings afterwards forever. Cleaning your PC will be a terrible heck. Absolutely not worth added value which you get from this utility. BEWARE!!!
