# bottomK(_:axis:k:name:)

Creates a BottomK operation and returns the value and indices tensors.

```
func bottomK(_ source: MPSGraphTensor, axis: Int, k: Int, name: String?) -> [MPSGraphTensor]
```

## Parameters

`source`

Tensor containing source data.

`axis`

The dimension along which to compute the BottomK values.

`k`

The number of largest values to return.

`name`

The name for the operation.

## Return Value

A valid MPSGraphTensor array of size 2.

## Discussion

Finds the k smallest values along the minor dimension of the input. The source must have
at least k elements along its minor dimension.
The first element of the result array corresponds to the bottom values, and the second
array corresponds to the indices of the bottom values.
