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

Creates a padding gradient operation and returns the result tensor.

## Declaration

```swift
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

Return Value A valid MPSGraphTensor object.
