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([ 62,  11, 140,  68], 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([[221, 145,  16],
    [161,  18,  78]], order=3^5)

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

In [6]: x = GF.Random([2, 3, 4]); x
Out[6]: 
GF([[[ 62, 119,  83, 224],
     [136, 162,  14, 215],
     [174, 134, 107, 134]],

    [[ 73, 101,  28,  21],
     [ 61,  12, 101, 224],
     [129,  14, 143, 164]]], order=3^5)

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

In [8]: x = GF.Random(()); x
Out[8]: GF(191, order=3^5)

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