## GET WITHIN DISTANCE

### Description

Calculate the energy distance within a data set.

### Usage

    getWithin(alpha_, X_)

### Arguments

`alpha_` | A weighting parameter used for calculating the energy distance. This value should be in (0,2].
`X_` | A n by d matrix of the n d-dimensional observations.

### Value

The returned value is a real number indicating the energy distance within the given data set.
