Methods

zero :: Num a => f a

The zero vector

default zero :: (GAdditive (Rep1 f), Generic1 f, Num a) => f a

(^+^) :: Num a => f a -> f a -> f a infixl 6

Compute the sum of two vectors

>>> V2 1 2 ^+^ V2 3 4
V2 4 6

(^-^) :: Num a => f a -> f a -> f a infixl 6

Compute the difference between two vectors

>>> V2 4 5 ^-^ V2 3 1
V2 1 4

lerp :: Num a => a -> f a -> f a -> f a

Linearly interpolate between two vectors.

liftU2 :: (a -> a -> a) -> f a -> f a -> f a

Apply a function to merge the 'non-zero' components of two vectors, unioning the rest of the values.

• For a dense vector this is equivalent to liftA2.
• For a sparse vector this is equivalent to unionWith.

default liftU2 :: Applicative f => (a -> a -> a) -> f a -> f a -> f a

liftI2 :: (a -> b -> c) -> f a -> f b -> f c

Apply a function to the components of two vectors.

• For a dense vector this is equivalent to liftA2.
• For a sparse vector this is equivalent to intersectionWith.
