# padGradient(withIncomingGradientTensor:sourceTensor:paddingMode:leftPadding:rightPadding:name:)

Creates a padding gradient operation and returns the result tensor.

```
func padGradient(withIncomingGradientTensor incomingGradientTensor: MPSGraphTensor, sourceTensor: MPSGraphTensor, paddingMode: MPSGraphPaddingMode, leftPadding: [NSNumber], rightPadding: [NSNumber], name: String?) -> MPSGraphTensor
```

## Parameters

`incomingGradientTensor`

The input gradient tensor.

`sourceTensor`

The input tensor of the forward pass.

`paddingMode`

The parameter that defines the padding mode.

`leftPadding`

The parameter that defines how much padding the operation applies to the input tensor before each dimension - must be of size `rank(tensor)`.

`rightPadding`

The parameter that defines how much padding the operation applies to the input tensor after each dimension - must be of size `rank(tensor)`.

`name`

The name for the operation.

## Return Value

A valid MPSGraphTensor object.
