## ScatterElementsUpdate <a name="ScatterElementsUpdate"></a> {#openvino_docs_ops_movement_ScatterElementsUpdate_3}

**Versioned name**: *ScatterElementsUpdate-3*

**Category**: Data movement operations

**Short description**: Creates a copy of the first input tensor with updated elements specified with second and third input tensors.

**Detailed description**: For each entry in `updates`, the target index in `data` is obtained by combining the corresponding entry in
`indices` with the index of the entry itself: the index-value for dimension equal to `axis` is obtained from the value of the corresponding entry in
`indices` and the index-value for dimension not equal to `axis` is obtained from the index of the entry itself.

For instance, in a 3D tensor case, the update corresponding to the `[i][j][k]` entry is performed as below:

```
output[indices[i][j][k]][j][k] = updates[i][j][k] if axis = 0,
output[i][indices[i][j][k]][k] = updates[i][j][k] if axis = 1,
output[i][j][indices[i][j][k]] = updates[i][j][k] if axis = 2
```

`update` tensor dimensions are less or equal to the corresponding `data` tensor dimensions. 

**Attributes**: *ScatterElementsUpdate* does not have attributes.

**Inputs**:

*   **1**: `data` tensor of arbitrary rank `r` and of type *T*. Required.

*   **2**: `indices` tensor with indices of type *T_IND*. The rank of the tensor is equal to the rank of `data` tensor.
All index values are expected to be within bounds `[0, s - 1]` along axis of size `s`. If multiple indices point to the
same output location then the order of updating the values is undefined. If an index points to non-existing output
tensor element or is negative then exception is raised. Required.

*   **3**: `updates` tensor of shape equal to the shape of `indices` tensor and of type *T*. Required.

*   **4**: `axis` tensor with scalar or 1D tensor with one element of type *T_AXIS* specifying axis for scatter.
The value can be in range `[-r, r - 1]` where `r` is the rank of `data`. Required.

**Outputs**:

*   **1**: tensor with shape equal to `data` tensor of the type *T*.

**Types**

* *T*: any numeric type.

* *T_IND*: any integer numeric type.

* *T_AXIS*: any integer numeric type.
