Types

type C

type C hyperplane.HP

C defines an N-dimensional linear constraint of the (standard) form embedded in N-dimensional ambient space.

A • X <= B

For two dimensions, this is

a_x * x + a_y * y <= b

func New

func New(p vector.V, n vector.V) *C

func (C) A

func (c C) A() []float64

A returns the A vector of the contraint; returns [a, b] in the 2D case.

func (C) B

func (c C) B() float64

B returns the bound on the constraint.

func (C) In

func (c C) In(v vector.V) bool
