Integral package:Yampa

integral :: (Fractional s, VectorSpace a s) => SF a a
Yampa FRP.Yampa FRP.Yampa.Integration
Integration using the rectangle rule.
imIntegral :: (Fractional s, VectorSpace a s) => a -> SF a a
Yampa FRP.Yampa FRP.Yampa.Integration
"Immediate" integration (using the function's value at the current time).
impulseIntegral :: (Fractional k, VectorSpace a k) => SF (a, Event a) a
Yampa FRP.Yampa FRP.Yampa.Integration
Integrate the first input signal and add the discrete accumulation (sum) of the second, discrete, input signal.
loopIntegral :: (Fractional s, VectorSpace c s) => SF (a, c) (b, c) -> SF a b
Yampa FRP.Yampa FRP.Yampa.Loop
Loop by integrating the second value in the pair and feeding the result back. Because the integral at time 0 is zero, this is always well defined.
