signalsmith::curves::Cubic< Sample > Class Template Reference

#include <curves.h>

Detailed Description

template<typename Sample = double>
class signalsmith::curves::Cubic< Sample >

A real-valued cubic curve. It has a "start" point where accuracy is highest.

Method Details

dx()

template<typename Sample = double>

Cubic signalsmith::curves::Cubic< Sample >::dx ( ) const

inline

Differentiate.

hermite()

template<typename Sample = double>

static Cubic signalsmith::curves::Cubic< Sample >::hermite ( Sample  x0, Sample  x1, Sample  y0, Sample  y1, Sample  g0, Sample  g1  )

inlinestatic

Cubic segment based on start/end values and gradients.

smooth()

template<typename Sample = double>

static Cubic signalsmith::curves::Cubic< Sample >::smooth ( Sample  x0, Sample  x1, Sample  x2, Sample  x3, Sample  y0, Sample  y1, Sample  y2, Sample  y3, bool  monotonic = false  )

inlinestatic

Cubic segment (valid between x1 and x2), which is smooth when applied to an adjacent set of points.

If x0 == x1 or x2 == x3 it will choose a gradient which continues in a quadratic curve, or 0 if the point is a local minimum/maximum.

start()

template<typename Sample = double>

Sample signalsmith::curves::Cubic< Sample >::start ( ) const

inline

The reference x-value, used as the centre of the cubic expansion.
