      Args:
          x (Variable): An input variable.
          min (Variable): A min variable by which `x` is clipped. Note that the shape of `min` must be the same as `x`'s.
          max (Variable): A max variable by which `x` is clipped. Note that the shape of `max` must be the same as `x`'s
  
      Returns:
          ~nnabla.Variable: N-D array.
