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([ 83, 191, 192,  28], 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([[ 89, 136, 179],
      [ 94, 161,  92]], order=3^5)
  
  In [5]: x.shape
  Out[5]: (2, 3)
  
  In [6]: x = GF.Random([2, 3, 4]); x
  Out[6]: 
  GF([[[ 70,  10,  50, 216],
       [ 29, 211, 173, 100],
       [171,  65,  12,  38]],
  
      [[195,  23, 118,  49],
       [181,  51, 183, 159],
       [ 43,  21,  93,  50]]], order=3^5)
  
  In [7]: x.shape
  Out[7]: (2, 3, 4)
  
  In [8]: x = GF.Random(()); x
  Out[8]: GF(69, order=3^5)
  
  In [9]: x.shape
  Out[9]: ()
