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([207,   7, 172,  35], 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([[154,  14,  56],
        [ 74, 223, 157]], order=3^5)
    
    In [5]: x.shape
    Out[5]: (2, 3)
    
    In [6]: x = GF.Random([2, 3, 4]); x
    Out[6]: 
    GF([[[124, 100,  24, 194],
         [230,  73,  19,  79],
         [120,  67, 134, 210]],
    
        [[128, 113,  60, 161],
         [198, 183, 152,  24],
         [  3,  84, 214, 197]]], order=3^5)
    
    In [7]: x.shape
    Out[7]: (2, 3, 4)
    
    In [8]: x = GF.Random(()); x
    Out[8]: GF(145, order=3^5)
    
    In [9]: x.shape
    Out[9]: ()
