## Detailed Description

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

A class representing a polynomial.

## ◆ Polynomial() [1/5]

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

Creates a new polynomial which will always evaluate to zero.

## ◆ Polynomial() [2/5]

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

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.

## ◆ 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});

## ◆ operator=() [1/2]

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

Creates a copy of another polynomial.

## ◆ operator=() [2/2]

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

Creates a copy of another polynomial.

## ◆ operator[]() [1/2]

template<typename FloatingType >
 FloatingType dsp::Polynomial< FloatingType >::operator[] ( int index ) const
noexcept

## ◆ operator[]() [2/2]

template<typename FloatingType >
 FloatingType & dsp::Polynomial< FloatingType >::operator[] ( int index )
noexcept

Returns a single coefficient of the receiver for modifying.

## ◆ operator()()

template<typename FloatingType >
 FloatingType dsp::Polynomial< FloatingType >::operator() ( FloatingType x ) const
noexcept

Evaluates the value of the polynomial at a single point x.

## ◆ getOrder()

template<typename FloatingType >
 int dsp::Polynomial< FloatingType >::getOrder ( )
noexcept

Returns the order of the polynomial.

## ◆ withGain()

template<typename FloatingType >
 Polynomial< FloatingType > dsp::Polynomial< FloatingType >::withGain ( double gain ) const

Returns the polynomial with all its coefficients multiplied with a gain factor.

## ◆ getSumWith()

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

Returns the sum of this polynomial with another.

Referenced by dsp::Polynomial< FloatingType >::getSumWith().

## ◆ getProductWith()

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

computes the product of two polynomials and return the result
