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([ 27,  90, 105, 214], 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([[  8,  77,  22],
        [129, 185, 197]], order=3^5)
    
    In [5]: x.shape
    Out[5]: (2, 3)
    
    In [6]: x = GF.Random([2, 3, 4]); x
    Out[6]: 
    GF([[[115, 238,  25, 153],
         [ 21, 181, 190, 212],
         [ 90, 170, 220,   2]],
    
        [[221, 100, 104,  48],
         [ 29,  73, 242, 177],
         [ 75,  62,   4, 147]]], order=3^5)
    
    In [7]: x.shape
    Out[7]: (2, 3, 4)
    
    In [8]: x = GF.Random(()); x
    Out[8]: GF(107, order=3^5)
    
    In [9]: x.shape
    Out[9]: ()
