# power(_:_:name:)

Returns the elementwise result of raising the first tensor to the power of the second tensor.

## Declaration

```swift
func power(_ primaryTensor: MPSGraphTensor, _ secondaryTensor: MPSGraphTensor, name: String?) -> MPSGraphTensor
```

## Parameters

- `primaryTensor`: The LHS tensor of the binary Op.
- `secondaryTensor`: The RHS tensor of the binary Op.
- `name`: An optional string which serves as an identifier for the operation.

## Return Value

Return Value A valid MPSGraphTensor object containing the elementwise result of the applied operation.

## Discussion

Discussion This operation creates a power operation and returns the result tensor. It supports broadcasting as well. resultTensor = pow(primaryTensor, secondaryTensor)
