Detailed Description

template<typename FloatingType>
class juce::dsp::Polynomial< FloatingType >

A class representing a polynomial.

@tags{DSP}

Constructor & Destructor Documentation

Polynomial() [1/5]

template<typename FloatingType >

juce::dsp::Polynomial< FloatingType >::Polynomial ( )

inline

Creates a new polynomial which will always evaluate to zero.

References juce::Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >::add(), and juce::dsp::Polynomial< FloatingType >::coeffs.

Polynomial() [2/5]

template<typename FloatingType >

juce::dsp::Polynomial< FloatingType >::Polynomial ( const FloatingType *  coefficients, int  numCoefficients  )

inline

Creates a new polynomial with given coefficients.

Parameters

numCoefficients	The number of coefficients stored in coefficients. This is also the order of the returned polynomial.
coefficients	The coefficients which will be used by the newly created polynomial. The Polynomial class will keep a private copy of the coefficients.

References juce::dsp::Polynomial< FloatingType >::coeffs, juce::Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >::isEmpty(), and jassert.

Polynomial() [3/5]

template<typename FloatingType >

juce::dsp::Polynomial< FloatingType >::Polynomial ( const Polynomial< FloatingType > &  )

default

Creates a copy of another polynomial.

Polynomial() [4/5]

template<typename FloatingType >

juce::dsp::Polynomial< FloatingType >::Polynomial ( Polynomial< FloatingType > &&  )

default

Creates a copy of another polynomial.

Polynomial() [5/5]

template<typename FloatingType >

template<typename... Values>

juce::dsp::Polynomial< FloatingType >::Polynomial ( Values...  items )

inline

Creates a new polynomial with coefficients by a C++11 initializer list.

This function can be used in the following way: Polynomial<float> p ({0.5f, -0.3f, 0.2f});
