numpy.unravel_index(indices, dims, order='C')
-
Converts a flat index or array of flat indices into a tuple of coordinate arrays.
Parameters: indices : array_like
An integer array whose elements are indices into the flattened version of an array of dimensions
dims
. Before version 1.6.0, this function accepted just one index value.dims : tuple of ints
The shape of the array to use for unraveling
indices
.order : {?C?, ?F?}, optional
Determines whether the indices should be viewed as indexing in row-major (C-style) or column-major (Fortran-style) order.
New in version 1.6.0.
Returns: unraveled_coords : tuple of ndarray
Each array in the tuple has the same shape as the
indices
array.See also

>>> np.unravel_index([22, 41, 37], (7,6)) (array([3, 6, 6]), array([4, 5, 1])) >>> np.unravel_index([31, 41, 13], (7,6), order='F') (array([3, 6, 6]), array([4, 5, 1]))
>>> np.unravel_index(1621, (6,7,8,9)) (3, 1, 4, 1)
