std::floating_point TData = float¶

The data type for the centroid coordinates

template<std::size_t Ndim, std::floating_point TData = float>
using Centroids = std::vector<Centroid<Ndim, TData>>¶

Type alias for a collection of centroids in Ndim dimensions.

Template Parameters:¶

std::size_t Ndim¶

The number of dimensions of the Centroids

std::floating_point TData = float¶

The data type for the centroid coordinates

Functions¶

template<std::size_t Ndim, std::floating_point TData = float>
inline Centroid<Ndim, TData> cluster_centroid(const clue::PointsHost<Ndim, TData> &points, std::size_t cluster_id)¶

Compute the centroid of a specific cluster from the given Points.

Template Parameters:¶

The data type for the point coordinates

Parameters:¶

const clue::PointsHost<Ndim, TData> &points¶

The PointsHost object containing the points

std::size_t cluster_id¶

The ID of the cluster for which to compute the centroid

Returns:¶

The centroid of the specified cluster as an array of floating points

template<std::size_t Ndim, std::floating_point TData = float>
inline Centroids<Ndim, TData> cluster_centroids(const clue::PointsHost<Ndim, TData> &points)¶

std::floating_point TData = float¶

The data type for the point coordinates

Parameters:¶

const clue::PointsHost<Ndim, TData> &points¶

The PointsHost object containing the points

Returns:¶

A vector of centroids, one for each cluster
