Class GenericGFPoly

Represents a polynomial whose coefficients are elements of a GF. Instances of this class are immutable.

Much credit is due to William Rucklidge since portions of this code are an indirect port of his C++ Reed-Solomon implementation.

  • throws

    IllegalArgumentException if argument is null or empty, or if leading coefficient is 0 and this is not a constant polynomial (that is, it is not the monomial "0")

    Parameters
