galois.typing.ShapeLike

A Union representing objects that can be coerced into a NumPy shape tuple.

Union

  • int: The size of a 1-D array.

    In [1]: GF = galois.GF(3**5)
    
    In [2]: x = GF.Random(4); x
    Out[2]: GF([224,  94, 126,  73], order=3^5)
    
    In [3]: x.shape
    Out[3]: (4,)
    
  • Sequence [ int ]: An iterable of integer dimensions. Tuples or lists are allowed. An empty iterable, () or [], represents a 0-D array (scalar).

    In [4]: x = GF.Random((2, 3)); x
    Out[4]: 
    GF([[ 24,  58, 216],
        [ 53, 129, 172]], order=3^5)
    
    In [5]: x.shape
    Out[5]: (2, 3)
    
    In [6]: x = GF.Random([2, 3, 4]); x
    Out[6]: 
    GF([[[ 55, 187, 155, 233],
         [240, 120,  58,  38],
         [ 93, 153, 197,   5]],
    
        [[  2,  83, 168,  54],
         [ 91,  19, 197, 197],
         [173, 175, 239,  99]]], order=3^5)
    
    In [7]: x.shape
    Out[7]: (2, 3, 4)
    
    In [8]: x = GF.Random(()); x
    Out[8]: GF(34, order=3^5)
    
    In [9]: x.shape
    Out[9]: ()
