Improvements ============ +`np.digitize` using binary search +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +`np.digitize` is now implemented in terms of `np.searchsorted`. This means +that a binary search is used to bin the values, which scales much better +for larger number of bins than the previous linear search. It also removes +the requirement for the input array to be 1-dimensional. + `np.poly` now casts integer inputs to float ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ `np.poly` will now cast 1-dimensional input arrays of integer type to double |
