array_split.split.shape_factors¶

array_split.split.shape_factors(n, dim=2)[source]¶

Returns a numpy.ndarray of factors f such that (len(f) == dim) and (numpy.product(f) == n). The returned factors are as square (cubic, etc) as possible. For example:

>>> shape_factors(24, 1)
array([24])
>>> shape_factors(24, 2)
array([4, 6])
>>> shape_factors(24, 3)
array([2, 3, 4])
>>> shape_factors(24, 4)
array([2, 2, 2, 3])
>>> shape_factors(24, 5)
array([1, 2, 2, 2, 3])
>>> shape_factors(24, 6)
array([1, 1, 2, 2, 2, 3])

Parameters:	n (`int`) – Integer which is factored into `dim` factors. dim (`int`) – Number of factors.
Return type:	`numpy.ndarray`
Returns:	A `(dim,)` shaped array of integers which are factors of `n`.
