# scatterND(withUpdatesTensor:indicesTensor:shape:batchDimensions:name:)

Creates a ScatterND operation and returns the result tensor.

```
func scatterND(withUpdatesTensor updatesTensor: MPSGraphTensor, indicesTensor: MPSGraphTensor, shape: [NSNumber], batchDimensions: Int, name: String?) -> MPSGraphTensor
```

## Parameters

`updatesTensor`

Tensor containing slices to be inserted into the result tensor.

`indicesTensor`

Tensor containg the result indices to insert slices at

`shape`

The shape of the result tensor.

`batchDimensions`

The number of batch dimensions

`name`

The name for the operation.

## Return Value

A valid MPSGraphTensor object

## Discussion

Scatters the slices in updatesTensor to the result tensor along the indices in indicesTensor.
The scatter is defined as

```md
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},index_slice[0],...,index_slice[K-1]] = updates[i_{b0},...,i_{bB},i_{0},...,i_{Q-1}] 
```

Collisions will be summed, and slices not set by indices are set to 0. The tensors have the following shape requirements

```md
K <= P 
U = (P-K) + Q-1 
indices.shape[0:Q-1] = updates.shape[0:Q-1] 
updates.shape[Q:U] = res.shape[K:P] 
```
