## Detailed Description

For containing a Polynomial (in Nc, CF and TR), as a sum of Monomials. Note that a Monomial "is" TR^a*Nc^b*CF^c*int_part*cnum_part where int_part is an integer factor, cnum_part a complex numerical factor and a,b, and c integers (not necessarily positive). An empty Polynomial is defined as 1.

## ◆ Polynomial() [1/4]

 ColorFull::Polynomial::Polynomial ( )
inline

Default constructor, leaves polynomial empty=1.

## ◆ Polynomial() [2/4]

 ColorFull::Polynomial::Polynomial ( const std::string str )

Constructor allow setting the polynomial by using a string. Should be used as for example "Polynomial Poly("(-20*TR^(5))/Nc + 28*Nc*TR^(5) - 10*Nc^3*TR^(5)")". The Momomials should be separated by + or -, see also the Monomial string constructor.

## ◆ Polynomial() [3/4]

 ColorFull::Polynomial::Polynomial ( double dnum )

Constructor allowing setting the Polynomial using a double. The Polynomial gets one Monomial where the real part of cnum_part gets the value of dnum.

## ◆ Polynomial() [4/4]

 ColorFull::Polynomial::Polynomial ( int num )

Constructor allowing setting the Polynomial using an int. The Polynomial gets one Monomial where int_part has the value num.

## ◆ append()

 void ColorFull::Polynomial::append ( const Monomial Mon )
inline

## ◆ at() [1/2]

 const Monomial& ColorFull::Polynomial::at ( int i ) const
inline

Returns Monomial at place i.

## ◆ at() [2/2]

 Monomial& ColorFull::Polynomial::at ( int i )
inline

Returns Monomial at place i.

## ◆ clear()

 void ColorFull::Polynomial::clear ( )
inline

Erases info in polynomial.

## ◆ conjugate()

 void ColorFull::Polynomial::conjugate ( )

Take complex conjugate of the polynomial. Note that this changes the Polynomial itself.

## ◆ empty()

 bool ColorFull::Polynomial::empty ( ) const
inline

Is the polynomial empty?

## ◆ erase()

 void ColorFull::Polynomial::erase ( int i )
inline

Erases the Monomial at place i.

## ◆ normal_order()

 void ColorFull::Polynomial::normal_order ( )

Orders terms in Polynomial in a unique form, first according to pow_Nc+pow_CF, then according to pow_Nc (for same pow_Nc+pow_CF) then according to int_part*num, then according to int_part, and finally according to pow_TR.

 void ColorFull::Polynomial::read_in_Polynomial ( std::string filename )

Function for reading in the Polynomial from the file filename, uses Polynomial_of_str.

## ◆ remove_CF()

 void ColorFull::Polynomial::remove_CF ( )

Replaces CF with TR*Nc-TR/Nc.

## ◆ simplify()

 void ColorFull::Polynomial::simplify ( )

Collects terms with same power of TR and Nc and Cf.

## ◆ size()

 int ColorFull::Polynomial::size ( ) const
inline

Returns the number of terms in the Polynomial.

## ◆ write_out_Polynomial()

 void ColorFull::Polynomial::write_out_Polynomial ( std::string filename ) const

Function for writing out the Polynomial to a file with name filename.

## ◆ poly

 polynomial ColorFull::Polynomial::poly

Contains the polynomial, a sum of Monomials, as an std::vector of Monomials. An empty Polynomial is defined as 1, to get 0, multiply with 0.
