Documentation
data T t y Source
interpolation as needed for resampling
constant :: T t ySource
Consider the signal to be piecewise constant.
linear :: C t y => T t ySource
Consider the signal to be piecewise linear.
cubic :: (C t, C t y) => T t ySource
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.
piecewise :: C t y => Int -> [t -> t] -> T t ySource
List of functions must be non-empty.
piecewiseConstant :: C t y => T t ySource
piecewiseLinear :: C t y => T t ySource
piecewiseCubic :: (C t, C t y) => T t ySource
functionSource
:: C t y
=> (Int, Int)(left extent, right extent), e.g. (1,1) for linear hat
-> t -> t
-> T t y
with this wrapper you can use the collection of interpolating functions from Donadio's DSP library
