# gatherND(withUpdatesTensor:indicesTensor:batchDimensions:name:)

Creates a GatherND operation and returns the result tensor.

## Declaration

```swift
func gatherND(withUpdatesTensor updatesTensor: MPSGraphTensor, indicesTensor: MPSGraphTensor, batchDimensions: Int, name: String?) -> MPSGraphTensor
```

## Parameters

- `updatesTensor`: Tensor containing slices to be inserted into the result tensor.
- `indicesTensor`: Tensor containg the updates indices to read slices from
- `batchDimensions`: The number of batch dimensions
- `name`: The name for the operation.

## Return Value

Return Value A valid MPSGraphTensor object

## Discussion

Discussion Gathers the slices in updatesTensor to the result tensor along the indices in indicesTensor. The gather is defined as B = batchDims  U = updates.rank - B  P = res.rank - B  Q = inds.rank - B  K = inds.shape[-1]  index_slice = indices[i_{b0},...,i_{bB},i_{0},..,i_{Q-1}]  res[i_{b0},...,i_{bB},i_{0},...,i_{Q-1}] = updates[i_{b0},...,i_{bB},index_slice[0],...,index_slice[K-1]]  The tensors have the following shape requirements U > 0; P > 0; Q > 0  K <= U  P = (U-K) + Q-1  indices.shape[0:Q-1] = res.shape[0:Q-1]  res.shape[Q:P] = updates.shape[K:U]
