galois.ReedSolomon.generator_poly

property galois.ReedSolomon.generator_poly : Poly

The generator polynomial \(g(x)\) whose roots are roots.

Examples¶

In [1]: rs = galois.ReedSolomon(15, 9); rs
Out[1]: <Reed-Solomon Code: [15, 9, 7] over GF(2^4)>

In [2]: rs.generator_poly
Out[2]: Poly(x^6 + 7x^5 + 9x^4 + 3x^3 + 12x^2 + 10x + 12, GF(2^4))

Evaluate the generator polynomial at its roots.

In [3]: rs.generator_poly(rs.roots)
Out[3]: GF([0, 0, 0, 0, 0, 0], order=2^4)
