cupy.lexsort¶

cupy.lexsort(keys)[source]¶

Perform an indirect sort using an array of keys.

Parameters:	keys (cupy.ndarray) – `(k, N)` array containing `k` `(N,)`-shaped arrays. The `k` different “rows” to be sorted. The last row is the primary sort key.
Returns:	Array of indices that sort the keys.
Return type:	cupy.ndarray

Note

For its implementation reason, cupy.lexsort currently supports only keys with their rank of one or two and does not support axis parameter that numpy.lexsort supports.
