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 : tuple of ints The shape of the array to use for unraveling 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 |
