  • Method Details

    • mult

      IntegerPolynomial mult(IntegerPolynomial poly2)
      Multiplies the polynomial by an IntegerPolynomial, taking the indices mod N.
      Parameters:
      poly2 - a polynomial
      Returns:
      the product of the two polynomials

    • mult

      IntegerPolynomial mult(IntegerPolynomial poly2, int modulus)
      Multiplies the polynomial by an IntegerPolynomial, taking the coefficient values mod modulus and the indices mod N.
      Parameters:
      poly2 - a polynomial
      modulus - 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 that mult(IntegerPolynomial, int) returns equal IntegerPolynomials). The new polynomial is guaranteed to be independent of the original.
      Returns:
      a new IntegerPolynomial.

    • mult

      BigIntPolynomial mult(BigIntPolynomial poly2)
      Multiplies the polynomial by a BigIntPolynomial, 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
