# afterAll

Run function after all functions finish running in the background.

## 📝 Syntax

* B = afterAll(F, fcn, n)

## 📥 Input argument

* F - Input Future object (scalar or array).
* fcn - Function handle: Function to run after all input futures.
* n - Number of output arguments.

## 📤 Output argument

* B - AfterAllFuture object.

## 📄 Description

B = afterAll(F, fcn, n) returns a AfterAllFuture objectB.

Functionfcn is automatically runned after all elements in the Future arrayF were finished.

If any of the elements in F encounters an error, the Error property of B contains an error.

## 💡 Example

```matlab
pool = backgroundPool()
fptrRand = str2func('rand')
fptrMax = str2func('@(r) max(r)')
fptrMin = str2func('@(r) min(r)')
for idx= 1:10
    f(idx) = parfeval(pool, fptrRand, 1, 1000, 1);
end
maxFuture = afterEach(f, fptrMax, 1);
minFuture = afterAll(maxFuture, fptrMin, 1);
fetchOutputs(minFuture)
fetchOutputs(maxFuture)
```
