priority

Change the priority of the MATLAB Process programatically.

Description

**WINDOWS only - must be compiled before use**

If you want to do some heavy processing and you don't want your computer to get all sluggish whilst it's going on, you can use this tool thusly:

pri=priority('l') % set priority to low
<do processing>
priority(pri) % set it back

• MATLAB release: MATLAB 7.5 (R2007b)
• Other requirements: Win95 or WinNT 3.1 or greater. More options work with Win2000 or later.

Nice! Confirmed to work on win2k SP3.

Thanks,

It works

[E Lehmann]

good work! very useful!

[Cleber Inacio]

Good, but doesnt work on mine. I just cant set to above normal... win98 matlabR12.

Been using this for 9 years every day as part of my startup script so that long-running MATLAB programs don't hog my computer. Thanks!

Works when I use your .dll, but I can't get the .c code to compile. I was hoping to alter your .c code to get maximum priority.

[Alan]

Any ideas on how to get this working on Windows 7?

Hi Alan

Works for me on Windows 7 - what's the problem?

Perhaps you need to be an Administrator to change process priorities? Can you change the priority using Task Manager?

[Alan]

Ben: Got it solved. It wasn't Windows 7 that was the problem. Instead, I was on 64-bit Matlab R2010b and it wanted a 64-bit binary. Recompiled it with a "mex priority.cpp" and all was working.

Side note: it is now "mex -setup", not "mex setup" as is says in your readme. Also, do you want the priority.mexw64 binary so you can include it with the distribution? Happy to share it.

[Ben Mitch]

Hmmm... do mathworks still allows us to upload binaries? I've a funny feeling they started outlawing that. We'll see, I just tried uploading a version with a win32 binary.

Cheers

[Ben Mitch]

No, they don't. I've uploaded just source, then. Thanks anyway

I've been using this for many years. It's a great little tool!
