# BNNSDataLayout3DLastMajor

A constant that represents a 3D last-major tensor.

## Declaration

```swift
var BNNSDataLayout3DLastMajor: BNNSDataLayout { get }
```

## Discussion

Discussion The value (i, j, k) is at index i * stride[0] + j * stride[1] + k * stride[2]. size[0] is the size of the first dimension (i). size[1] is the size of the second dimension (j). size[2] is the size of the third dimension (k).
