IntegerPolynomial mult(IntegerPolynomial poly2)
Multiplies the polynomial by anIntegerPolynomial
, taking the indices modN
.- Parameters:
poly2
- a polynomial- Returns:
- the product of the two polynomials
-
mult
IntegerPolynomial mult(IntegerPolynomial poly2, int modulus)
Multiplies the polynomial by anIntegerPolynomial
, taking the coefficient values modmodulus
and the indices modN
.- Parameters:
poly2
- a polynomialmodulus
- a modulus to apply- Returns:
- the product of the two polynomials
-
toIntegerPolynomial
IntegerPolynomial toIntegerPolynomial()
Returns a polynomial that is equal to this polynomial (in the sense thatmult(IntegerPolynomial, int)
returns equalIntegerPolynomial
s). The new polynomial is guaranteed to be independent of the original.- Returns:
- a new
IntegerPolynomial

mult
BigIntPolynomial mult(BigIntPolynomial poly2)
Multiplies the polynomial by aBigIntPolynomial
, taking the indices mod N. Does not change this polynomial but returns the result as a new polynomial.
Both polynomials must have the same number of coefficients.- Parameters:
poly2
- the polynomial to multiply by- Returns:
- a new polynomial
