Synopsis

Vector types

type Vector n e = Tensor '[n] e Source #

N-dimensional vector.

type VectorConstructor n e = TensorConstructor '[n] e Source #

Type of vector data constructor.

type IsVector n e = IsTensor '[n] e Source #

Construction

vector :: forall n e. IsVector n e => VectorConstructor n e Source #

Alias for a conrete vector data constructor.

Vector Operations

normalize :: Normalize n e => Vector n e -> NormalizedVector n e Source #

Normalize vector.

data NormalizedVector n e Source #

Normalized vector.

Instances
