docs: Calculate the relative maxima of `data`.
  
      .. versionadded:: 0.11.0
  
      Parameters
      ----------
      data : ndarray
          Array in which to find the relative maxima.
      axis : int, optional
          Axis over which to select from `data`.  Default is 0.
      order : int, optional
          How many points on each side to use for the comparison
          to consider ``comparator(n, n+x)`` to be True.
      mode : str, optional
          How the edges of the vector are treated.
          Available options are 'wrap' (wrap around) or 'clip' (treat overflow
          as the same as the last (or first) element).
          Default 'clip'.  See `numpy.take`.
  
      Returns
      -------
      extrema : ndarray
          Indices of the maxima, as an array of integers.

      --------
      argrelextrema, argrelmin
  
      Notes
      -----
      This function uses `argrelextrema` with np.greater as comparator.
