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.

Functions

Background Execution

`parfeval`	Run function in background
`backgroundPool`	Environment for running code in the background

Futures

`fetchOutputs`	Retrieve results from function running in the background
`afterEach`	Run function after each function finishes running in the background
`afterAll`	Run function after all functions finish running in the background
`cancel`	Stop function running in the background
`wait`	Wait for futures to complete
`fetchNext`	Retrieve next unread outputs from `Future` array
`Future`	Function scheduled to run

Data Queues

`send`	Send data to `DataQueue` or `PollableDataQueue`
`poll`	Retrieve data from `PollableDataQueue`
`afterEach`	Run function after data is received on `DataQueue`
`parallel.pool.DataQueue`	Send and automatically process data
`parallel.pool.PollableDataQueue`	Send and manually retrieve data
