Functions

func Abs

func Abs[T types.RealNumbers](v []T) (res []T, err error)

func Add

func Add[T types.RealNumbers](v1, v2 []T) ([]T, error)

func Cast

func Cast[I types.RealNumbers, O types.RealNumbers](in []I) (out []O, err error)

func Compare

func Compare[T types.RealNumbers](v1, v2 []T) int

Compare returns an integer comparing two arrays/vectors lexicographically. TODO: this function might not be correct. we need to compare using tolerance for float values. TODO: need to check if we need len(v1)==len(v2) check.
