Methods

• dot :: Num a => f a -> f a -> a

  Compute the inner product of two vectors or (equivalently) convert a vector f a into a covector f a -> a.

• quadrance :: Num a => f a -> a

  Compute the squared norm. The name quadrance arises from Norman J. Wildberger's rational trigonometry.

• qd :: Num a => f a -> f a -> a

  Compute the quadrance of the difference

• distance :: Floating a => f a -> f a -> a

  Compute the distance between two vectors in a metric space

• norm :: Floating a => f a -> a

  Compute the norm of a vector in a metric space

• signorm :: Floating a => f a -> f a

  Convert a non-zero vector to unit vector.
