Detailed Description

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

A class representing a polynomial.

Constructor & Destructor Documentation

◆ Polynomial() [1/5]

template<typename FloatingType >
dsp::Polynomial< FloatingType >::Polynomial ( )

Creates a new polynomial which will always evaluate to zero.

References Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >::add().

◆ Polynomial() [2/5]

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

Creates a new polynomial with given coefficients.

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

References Array< ElementType, TypeOfCriticalSectionToUse, minimumAllocatedSize >::isEmpty(), and jassert.

◆ Polynomial() [3/5]

template<typename FloatingType >
dsp::Polynomial< FloatingType >::Polynomial ( const Polynomial< FloatingType > & )
default

Creates a copy of another polynomial.

◆ Polynomial() [4/5]

template<typename FloatingType >
dsp::Polynomial< FloatingType >::Polynomial ( Polynomial< FloatingType > && )
default

Creates a copy of another polynomial.

◆ Polynomial() [5/5]

template<typename FloatingType >
template<typename... Values>
dsp::Polynomial< FloatingType >::Polynomial ( Values... items)

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});
