What is the alternate of numpy.digitize() function in Julia?

Question

I would like to know, how may I replicate the numpy.digitize() functionality in julia? I am trying to convert this python example to Julia.

Python Example

x = np.array([0.2, 6.4, 3.0, 1.6])
bins = np.array([0.0, 1.0, 2.5, 4.0, 10.0])
inds = np.digitize(x, bins)

Output: array([1, 4, 3, 2], dtype=int64)

I tried using searchsorted function in Julia but it doesn't replicate the output form python. Please suggest a solution to this problem.

Thanks in advance!!

Answer 1

You may use searchsortedlast with broadcasting:

julia> x = [0.2, 6.4, 3.0, 1.6]
4-element Array{Float64,1}:
 0.2
 6.4
 3.0
 1.6

julia> bins = [0.0, 1.0, 2.5, 4.0, 10.0]
5-element Array{Float64,1}:
  0.0
  1.0
  2.5
  4.0
 10.0

julia> searchsortedlast.(Ref(bins), x)
4-element Array{Int64,1}:
 1
 4
 3
 2
