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([ 84, 198, 217, 107], 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([[ 22, 204,  60],
      [  6, 176, 216]], order=3^5)
  
  In [5]: x.shape
  Out[5]: (2, 3)
  
  In [6]: x = GF.Random([2, 3, 4]); x
  Out[6]: 
  GF([[[236, 230, 240,  92],
       [177, 229,  86, 110],
       [120, 145, 143, 170]],
  
      [[ 66,  12,  54, 232],
       [146, 169, 168, 179],
       [ 64,  92, 107,  70]]], order=3^5)
  
  In [7]: x.shape
  Out[7]: (2, 3, 4)
  
  In [8]: x = GF.Random(()); x
  Out[8]: GF(118, order=3^5)
  
  In [9]: x.shape
  Out[9]: ()
