func NewPoints

func NewPoints(n int, pgen func() *Point) *Points

func (*Points) CullByCompanions

func (p *Points) CullByCompanions(n int) *Points

CullByCompanions culls out the systems that are closest to each other.

func (*Points) CullByDistanceFromOrigin

func (p *Points) CullByDistanceFromOrigin() *Points

CullByDistanceFromOrigin culls out the systems that are farthest from the origin

func (*Points) CullByMinDistance

func (p *Points) CullByMinDistance(min float64) *Points

CullByMinDistance culls out the systems that are closest to each other

func (*Points) Length

func (p *Points) Length() int

Length returns the number of points.

func (*Points) MinAvgMax

func (p *Points) MinAvgMax() (min, avg, max float64)

MinAvgMax returns the minimum, average, and maximum average distances between neighbors

func (*Points) SetNeighbors

func (p *Points) SetNeighbors(n int)

func (*Points) SortByDistanceDesc

func (p *Points) SortByDistanceDesc(n int) *Points

SortByDistanceDesc sorts the points by average distance from neighbors, descending. N is the number of neighbors to use for distance.

func (*Points) SortByDistanceOrigin
