Hello everyone, I have following situation: I am running a simple simulation of motion. A point mass moving at a constant velocity in XY plane. Now, I need to call a function to capture an image. Image capturing function takes about 2 seconds. I need first simulation (motion) keep on running while running the image capturing function. Is there any parallel computing tool in MATLAB that could be run without hindering simulation platform? Please advise. Many thanks.

Parallel Computing Toolbox's batch capability may do the trick for you. Fire off the image capture as a batch job while performing the simulation in the main process.

Thanks very much Ken. Opening of batch program is quite time consuming!! Even for simple functions! it is taking significant time in MATLAB! This is not suitable for my first section of code. I was thinking of using 'parfor', would you be able to tell me how to set equal times for all statements inside 'parfor'. Thanks again.

You cannot set equal times for statements inside parfor()

You should consider using a timer()

Note: a timer sounds like all you would need in your situation. Timers can interrupt between any two lines of MATLAB source. Unless you are doing uninterpretable real-time work in the simulation, you likely do not need parallelism.
