galois.typing.ArrayLike¶

galois.typing.ArrayLike¶

A Union representing objects that can be coerced into a Galois field array.

Union

• IterableLike: A recursive iterable of iterables of elements.

In [1]: GF = galois.GF(3**5)

In [2]: GF([[17, 4], [148, 205]])
Out[2]: 
GF([[ 17,   4],
    [148, 205]], order=3^5)

# Mix and match integers and strings
In [3]: GF([["x^2 + 2x + 2", 4], ["x^4 + 2x^3 + x^2 + x + 1", 205]])
Out[3]: 
GF([[ 17,   4],
    [148, 205]], order=3^5)

• ndarray: A NumPy array of integers, representing finite field elements in their integer representation.

In [4]: x = np.array([[17, 4], [148, 205]]); x
Out[4]: 
array([[ 17,   4],
       [148, 205]])

In [5]: GF(x)
Out[5]: 
GF([[ 17,   4],
    [148, 205]], order=3^5)

• Array: A previously-created Array object. No coercion is necessary.
