> plot [Fun (sin.(pi*)) "sin", Fun (cos.(pi*)) "cos"]
Default plot interval is [-1,1].
Hatlab supports plotting of relations on the real numbers. The Hatlab.Relations module defines a small DSL for relations. The supported operations are:
r :: (Double -> Double -> Bool) -> String -> Relation
r defines a basic relation. Some operations on relations
are supported:
a .\/. b = a ∪ b
a ./\. b = a ∩ b
c a = complement of a
a .\. b = a minus b
We can plot relations with a similar command as for functions:
> let q = r (\x y -> x == y) "Line"
> let w = r (\x y -> x*x+y*y <= 1) "Disc"
> plot [q, w]
