'monitor': Set monitor status without stopping the processing.

2nd input: 'off' (default), 'on', 'standby'.

Moving the mouse etc. enables the monitor automatically.

'battery': Reply the battery related parameters for laptops.

Force: Optional argument to force the action:

'forceifhung': Close waiting and crashed applications. Dangerous.

EXAMPLES:

1. Try a poweroff, do not kill waiting applications:

WinPower('poweroff');

2. Force a poweroff (unsaved documents are lost!):

WinPower('poweroff', 'forceifhung');

3. Do not let the computer fall asleep during a long computation:

WinPower('Sleep', 'off'); Long_Calculation(); WinPower('Sleep', 'on');

4. Reboot the machine and after the user is logged in Matlab is started with

the bench() function:

WinPower('RebootMatlab', 'bench(2)');

5. Get the battery parameters:

Status = WinPower('BatteryStatus')

6. Switch off the monitor for 5 seconds:

WinPower('Monitor', 'off'); pause(5); WinPower('Monitor', 'on');

WinPower runs under Windows only. It can be compiled with MSVC2008/2010, but LCC shipped with Matlab 32bit fails. In case of troubles or for Matlab 6.5 download pre-compiled files:
