Synopsis

class Invert p where
- invert :: p wX wY -> p wY wX
invertFL :: Invert p => FL p wX wY -> RL p wY wX
invertRL :: Invert p => RL p wX wY -> FL p wY wX
dropInverses :: (Invert p, Eq2 p) => FL p wX wY -> Maybe (FL p wX wY)

Documentation

class Invert p where Source #

The invert operation must be self-inverse, i.e. an involution:

invert . invert = id
