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.
