Background Processing

Run code in the background and run other code at the same time

When you run code in MATLAB®, you must wait for that code to finish running before you can run other code. The background pool enables you to run code in the background and run other code at the same time. For instance, you can create apps that remain responsive while performing calculations in the background.

Use parfeval with the background pool to run a function in the background. parfeval immediately returns a Future object that represents the function running in the background. To get results from the Future, call fetchOutputs.
