Constructs the polynomial $f(x)=x$ over $\mathrm{GF}(p^m)$.

Parameters:¶

field: type[Array] | None = None¶

The Galois field $\mathrm{GF}(p^m)$ the polynomial is over. The default is None which corresponds to GF2.

Returns:¶

The polynomial $f(x)=x$.

Examples¶

Construct the identity polynomial over $\mathrm{GF}(2)$.

In [1]: galois.Poly.Identity()
Out[1]: Poly(x, GF(2))

Construct the identity polynomial over $\mathrm{GF}(3^5)$.

In [2]: GF = galois.GF(3**5)

In [3]: galois.Poly.Identity(GF)
Out[3]: Poly(x, GF(3^5))
