# MLCTensorDescriptor

A configuration object you use to create a tensor.

## Declaration

```swift
class MLCTensorDescriptor
```

## Overview

Overview This class contains the mathematical properties of a tensor, such as data type and shape. It also includes initializers that help you create a tensor descriptor for common use cases, such as convolutional neural networks and recurrent neural networks.
