# strides

An array of strides, in elements, one for each dimension of this tensor, if applicable.

## Declaration

```swift
var strides: MTLTensorExtents? { get }
```

## Discussion

Discussion You are responsible for ensuring strides meets the following requirements: The first element of strides must be 1. If usage contains machineLearning, the second element of strides must be aligned to 64 bytes, and for any i larger than 1, strides[i] must equal strides[i-1] * dimensions[i-1]. If dataType is a format MTLTensorDataType, for any i greater than or equal to 1, strides[i] must be aligned to 128 bytes. This is not a requirement for non-format data types, but following this convention improves performance. This property is non-nil only for tensors created from a buffer.
