# multiArrays

A cloned data column of machine learning multi-arrays.

## Declaration

```swift
var multiArrays: MLDataColumn<MLDataValue.MultiArrayType>? { get }
```

## Return Value

Return Value A new data column if the underlying type of the column is MLDataValue.MultiArrayType; otherwise nil.

## Discussion

Discussion This property is functionally equivalent to passing MLDataValue.MultiArrayType .self to column(type:). Typically you ensure type is equal to MLDataValue.ValueType.multiArray before getting this property.
