normFst :: (Fractional a, Ord a) => [(a, b)] -> IO [(a, b)] Source #
Norms a tuples in a list by their first elements so that the greatest by an absolute value first element is equal to 1 (or -1). If all the first elements are zeros then prints a warning message and exits successfully.
normSnd :: (Fractional b, Ord b) => [(a, b)] -> IO [(a, b)] Source #
Norms a tuples in a list by their second elements so that the greatest by an absolute value second element is equal to 1 (or -1). If all the second elements are zeros then prints a warning message and exits successfully.
evalFstFV :: (Fractional a, Ord a, Eq b) => (a -> b) -> [a] -> IO [((a, b), (a, b))] Source #
A special function transformation to obtain the resulting list so that its first elements in the inner tuples are in a special way
normed to 1 (or -1) by normFst and the inner tuples are sequenced one by another as a 2D points of the generating function f :: a -> b.
To obtain non-empty result the given second argument must have at least two elements.
evalFstFVM :: (Fractional a, Ord a, Eq b) => (a -> IO b) -> [a] -> IO [((a, b), (a, b))] Source #
The same as evalFstFV but uses a monadic IO function f.
evalSndFV :: (Fractional b, Ord b, Eq a) => (a -> b) -> [a] -> IO [((a, b), (a, b))] Source #
A special function transformation to obtain the resulting list so that its second elements in the inner tuples are in a special way
normed to 1 (or -1) by normSnd and the inner tuples are sequenced one by another as a 2D points of the generating function f :: a -> b.
To obtain non-empty result the given second argument must have at least two elements. Is similar to evalFstFV.
evalSndFVM :: (Fractional b, Ord b, Eq a) => (a -> IO b) -> [a] -> IO [((a, b), (a, b))] Source #
The same as evalSndFV but uses a monadic IO function f.
