cupy.unravel_index¶
-
cupy.
unravel_index
(indices, dims, order='C')[source]¶ Converts array of flat indices into a tuple of coordinate arrays.
Parameters: - indices (cupy.ndarray) – An integer array whose elements are indices
into the flattened version of an array of dimensions
dims
. - dims (tuple of ints) – The shape of the array to use for unraveling indices.
- order ('C' or 'F') – Determines whether the indices should be viewed as indexing in row-major (C-style) or column-major (Fortran-style) order.
Returns: Each array in the tuple has the same shape as the indices array.
Return type: tuple of ndarrays
Examples
>>> cupy.unravel_index(cupy.array([22, 41, 37]), (7, 6)) (array([3, 6, 6]), array([4, 5, 1])) >>> cupy.unravel_index(cupy.array([31, 41, 13]), (7, 6), order='F') (array([3, 6, 6]), array([4, 5, 1]))
