derivative :: (RealFloat a, HasTime t s, Monoid e) => Wire s e m a aSource
Time derivative of the input signal.
- Depends: now.
- Inhibits: at singularities.
Arguments
| :: (Fractional a, HasTime t s) | |
| => a | Integration constant (aka start value). |
| -> Wire s e m a a |
Integrate the input signal over time.
- Depends: before now.
Arguments
| :: (Fractional a, HasTime t s) | |
| => (w -> a -> a) | Correction function. |
| -> a | Integration constant (aka start value). |
| -> Wire s e m (a, w) a |
Integrate the left input signal over time, but apply the given correction function to it. This can be used to implement collision detection/reaction.
The right signal of type w is the world value. It is just passed
to the correction function for reference and is not used otherwise.
The correction function must be idempotent with respect to the world
value: f w (f w x) = f w x. This is necessary and sufficient to
protect time continuity.
- Depends: before now.
