zeroPad :: C t => (T t y -> t -> T y -> a) -> y -> T t y -> t -> T y -> a | Source |
|
|
constantPad :: C t => (T t y -> t -> T y -> a) -> T t y -> t -> T y -> a | Source |
|
|
cyclicPad :: C t => (T t y -> t -> T y -> a) -> T t y -> t -> T y -> a | Source |
|
Only for finite input signals.

extrapolationPad :: C t => (T t y -> t -> T y -> a) -> T t y -> t -> T y -> a | Source |
|
The extrapolation may miss some of the first and some of the last points
|
|
single :: C t => T t y -> t -> T y -> y | Source |
|
|
multiRelative :: C t => T t y -> t -> T y -> T t -> T y | Source |
|
All values of frequency control must be non-negative.

|
The extrapolation may miss some of the first and some of the last points

Consider the signal to be piecewise constant.
|
|
|
Consider the signal to be piecewise linear.
|
|
|
Consider the signal to be piecewise cubic,
with smooth connections at the nodes.
It uses a cubic curve which has node values
x0 at 0 and x1 at 1 and derivatives
(x1-xm1)2 and (x2-x0)2, respectively.
You can see how it works
if you evaluate the expression for t=0 and t=1
as well as the derivative at these points.
