# allocate(initializingFrom:shape:batchSize:)

Returns a new n-dimensional array descriptor that’s initialized with a copy of the elements in the specified collection.

## Declaration

```swift
static func allocate<C>(initializingFrom source: C, shape: BNNS.Shape, batchSize: Int = 1) -> BNNSNDArrayDescriptor where C : Collection, C.Element : BNNSScalar
```

## Parameters

- `source`: The collection that provides the source elements.
- `shape`: The shape of n-dimensional array descriptor.
- `batchSize`: The number of batches of data.
