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

#include <curves.h>

Detailed Description

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

Smooth interpolation (optionally monotonic) between points, using cubic segments.

Example curve including a repeated point and an instantaneous jump. The curve is flat beyond the first/last points.

To produce a sharp corner, use a repeated point. The gradient is flat at the edges, unless you use repeated points at the start/end.

Types
using	Segment = Cubic<Sample>

Methods
void	clear ()
	Clear existing points and segments.
CubicSegmentCurve &	add (Sample x, Sample y, bool corner=false)
	Add a new point, but does not recalculate the segments. corner just writes the point twice, for convenience.
void	update (bool monotonic=false, bool extendGrad=true, Sample monotonicFactor=3)
	Recalculates the segments.
Sample	operator() (Sample x) const
	Reads a value out from the curve.
CubicSegmentCurve	dx () const
Sample	dx (Sample x) const
std::vector< Segment > &	segments ()
const std::vector< Segment > &	segments () const

Attributes
Sample	lowGrad = 0
Sample	highGrad = 0

Method Details

add()

template<typename Sample = double>

CubicSegmentCurve & signalsmith::curves::CubicSegmentCurve< Sample >::add ( Sample x, Sample y, bool corner = false )

inline

Add a new point, but does not recalculate the segments. corner just writes the point twice, for convenience.

clear()

template<typename Sample = double>

void signalsmith::curves::CubicSegmentCurve< Sample >::clear ( )

inline

Clear existing points and segments.

operator()()

template<typename Sample = double>

Sample signalsmith::curves::CubicSegmentCurve< Sample >::operator() ( Sample x ) const

inline

Reads a value out from the curve.

update()

template<typename Sample = double>
