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([ 54, 109, 195,  85], 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([[177, 105,  69],
      [128, 149,  99]], order=3^5)
  
  In [5]: x.shape
  Out[5]: (2, 3)
  
  In [6]: x = GF.Random([2, 3, 4]); x
  Out[6]: 
  GF([[[142, 192, 104,  90],
       [ 68,  42, 206,  80],
       [180, 135,  70, 209]],
  
      [[ 29, 213, 146, 241],
       [183,  90, 165, 110],
       [177,  25, 223, 162]]], order=3^5)
  
  In [7]: x.shape
  Out[7]: (2, 3, 4)
  
  In [8]: x = GF.Random(()); x
  Out[8]: GF(218, order=3^5)
  
  In [9]: x.shape
  Out[9]: ()
