Parallel scripts on MATLAB

I have two systems running on MATLAB: the control system and the computer vision system.

The control system needs to receive three variables generated by the computer vision system periodically. However, I can't single thread both systems, because the computer vision system latency is too high compared with the control system latency.

I tried to run each program in a different MATLAB session and use a .mat file as interface between both sessions, but it did not work.

I'm not familiar with the Parallel Computing Toolbox. So I was wondering if someone can help with this? Or at lest give a start up idea, because, as I've said, I will start to learn the Parallel Computing Toolbox now.

So @Diogo did you solve your problem? - Benoit_11
@Benoit_11, as my time to do the work is almost finishing, I came back to THE solution I was using before, two MATLAB sessions. Anyway, thanks for the help. Next time I will try to use your suggestion. - Diogo Cosin

I think the function in the Parallel Computing Toolbox you may be looking for is parfeval. It lets you spawn an asynchronous task, and get its result whenever it is ready.

In addition to parfeval as suggested by @Dima you might also want to look into labSendReceive and associated function like labSend and labReceive which allow to share data between individual workers in your parallel pool. I guess which one is best for you depends on the type of calculation you want to do.
