/**
 *
 * @brief   Clustering algorithm ROCK returns allocated clusters.
 * @details Caller should destroy returned result in 'pyclustering_package'.
 *
 * @param[in] p_sample: input data for clustering.
 * @param[in] p_radius: connectivity radius (similarity threshold).
 * @param[in] p_number_clusters: defines number of clusters that should be allocated from the input data set.
 * @param[in] p_threshold: value that defines degree of normalization that influences
 *             on choice of clusters for merging during processing.
 *
 * @return  Returns result of clustering - array of allocated clusters in the pyclustering package.
