Thread implemented in MATLAB in a timer
显示 更早的评论
Hello,
I have two processes (one for a camera that runs through a camera function and one for a robot that runs through a robot function), and I'd like to set up a thread to run them in parallel.
I'd like the robot process to run in the background if possible. I searched the internet and found parfeval but I don't really understand how it works.
I don't really understand how it works. Can you advise me on how to do this?

Hi Claire,
I understand that you want to run two processes in parallel: one for a camera function and another for a robot function, with the robot process running asynchronously in the background.
To achieve this, you can use MATLAB ‘parfeval’ function along with ‘parpool’ function. The MATLAB ‘parpool’ function starts a parallel pool of workers, while the MATLAB ‘parfeval’ function is used to run functions in the background.
To set this up, please refer to the steps given below.
- Start the parallel pool with two workers.
parpool(2);
- Run the camera and robot processes in the background.
f1 = parfeval(@cameraProcess, 0); % The second parameter represents number of output. ‘0’ means there is no output.
f2 = parfeval(@robotProcess, 0);
For more information, please refer to the MATLAB documentation for ‘parpool’ and ‘parfeval’ functions.

Additionally, you might find this MATLAB community discussion helpful.
Hope this helps in solving your query.
