The fixed-vector package uses a similar technique. The only trouble I'm
having is with converting Vec v (Double, Double) to [(Double, Double)] for
further use. I don't want to change all the code, but only the part where
the user provides me with arguments.
I'll keep looking into it. Thanks for the help.

There are a lot of ways to do this sort of thing, and which one you choose will depend on exactly what you're trying to do. For example, you can write something vaguely like
data Nat = Z | S Nat data SL (n :: Nat) a where Nil :: SL Z Cons :: a -> SL n a -> SL (S n) a
plot :: forall (n::Nat) . (SL n Double -> Double) -> SL n (Double, Double) -> IO () On Mar 11, 2015 5:45 PM, "Sumit Sahrawat, Maths & Computing, IIT (BHU)" < sumit.sahrawat.apm13@iitbhu.ac.in> wrote:
Hi everybody,
I have a function of type
plot :: ([Double] -> Double) -- A function to plot -> [(Double, Double)] -- Range for all arguments -> IO ()
I want to enforce the fact that ranges for all arguments should be provided. Is there a way to make the type system enforce it?
