dpnp.unravel_index¶

dpnp.unravel_index(indices, shape, order='C')[source]¶

Converts array of flat indices into a tuple of coordinate arrays.

For full documentation refer to numpy.unravel_index.

Parameters:

indices{dpnp.ndarray, usm_ndarray}

An integer array whose elements are indices into the flattened version of an array of dimensions shape.

shapetuple or list of ints

The shape of the array to use for unraveling indices.

order{None, "C", "F"}, optional

Determines whether the indices should be viewed as indexing in row-major (C-style) or column-major (Fortran-style) order.

Default: "C".

Returns:

unraveled_coordstuple of dpnp.ndarray: Each array in the tuple has the same shape as the indices array.

Examples

>>> import dpnp as np
>>> np.unravel_index(np.array([22, 41, 37]), (7, 6))
(array([3, 6, 6]), array([4, 5, 1]))
>>> np.unravel_index(np.array([31, 41, 13]), (7, 6), order="F")
(array([3, 6, 6]), array([4, 5, 1]))

>>> np.unravel_index(np.array(1621), (6, 7, 8, 9))
(array(3), array(1), array(4), array(1))
