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([147,  58,  38, 216], 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([[226, 114, 162],
    [ 68, 111, 146]], order=3^5)

In [5]: x.shape
Out[5]: (2, 3)

In [6]: x = GF.Random([2, 3, 4]); x
Out[6]: 
GF([[[184,  53, 150,  93],
     [167, 205,  37, 171],
     [ 97, 170, 145, 187]],

    [[190,  14, 229, 226],
     [178,  22,  80, 135],
     [119,  28,  33,  52]]], order=3^5)

In [7]: x.shape
Out[7]: (2, 3, 4)

In [8]: x = GF.Random(()); x
Out[8]: GF(16, order=3^5)

In [9]: x.shape
Out[9]: ()
