cf.Data.ndindex

Data.ndindex()

Return an iterator over the N-dimensional indices of the data array.

At each iteration a tuple of indices is returned, the last dimension is iterated over first.

Returns

itertools.product

An iterator over tuples of indices of the data array.

Examples

>>> d = cf.Data(np.arange(6).reshape(2, 3))
>>> print(d.array)
[[0 1 2]
 [3 4 5]]
>>> for i in d.ndindex():
...     print(i, d[i])
...
(0, 0) [[0]]
(0, 1) [[1]]
(0, 2) [[2]]
(1, 0) [[3]]
(1, 1) [[4]]
(1, 2) [[5]]

>>> d = cf.Data(9)
>>> for i in d.ndindex():
...     print(i, d[i])
...
() 9
