# SlidingWindows

A sequence of windows on a time series shaped array.

## Declaration

```swift
struct SlidingWindows<Scalar> where Scalar : MLShapedArrayScalar
```

## Overview

Overview The shape of each window in the sequence is [length, featureSize]. The sequence will return as many windows as fit in the input. For example, an input shaped array of shape [8, 1] using stride of 1 and length of 4 will produce 5 examples: [[1], [2], [3], [4]] [[2], [3], [4], [5]] [[3], [4], [5], [6]] [[4], [5], [6], [7]] [[5], [6], [7], [8]]
