Matlab 2010a not using entire CPU

post #1 of 5
Thread Starter 
I'm trying to do image rectification for stereo vision cams. I'm using 2 small 640x480 JPG images, but it's taking forever to get done! The worst part is matlab is only using 26% of the cpu. The load is alternating between 70% usage of one core or 20% usage of each of the 4 cores. Can't I force it to fully use my CPU? Or maybe direct the load to my GPU?

Have you tried setting the priority/affinity of the process as high as you can go?

I dont think Matlab is optimized for multicore processing, which is probably one of the reasons its not running as fast as it could be.
