      Parameters
      ----------
      x
          input array.
      threshold
          The value to threshold at.
      value
          The value to replace with.
      out
          optional output array, for writing the result to. It must have a shape that the
          inputs broadcast to.
  
      Returns
      -------
      ret
          an array containing the threshold activation of each element in ``x``.

      --------
