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.

Constructor & Destructor Documentation

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.

Member Function Documentation

append()

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

inline

Adding a Monomial term.

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.

read_in_Polynomial()

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.

Member Data Documentation

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.
