type Polynomial []fr.Element

Polynomial polynomial represented by coefficients bn254 fr field.

func (*Polynomial) Add

func (p *Polynomial) Add(p1, p2 Polynomial) *Polynomial

Add adds p1 to p2 This function allocates a new slice unless p == p1 or p == p2

func (*Polynomial) AddConstantInPlace

func (p *Polynomial) AddConstantInPlace(c *fr.Element)

AddConstantInPlace adds a constant to the polynomial, modifying p

func (*Polynomial) Clone

func (p *Polynomial) Clone() Polynomial

Clone returns a copy of the polynomial
