.. py:function:: apply_filter_to_array_with_nans_multidim(a, freq: float, fr: float, N: int = 1)

   Power-spectrum of signal.

   Compute the power spectrum of a signal and its dominant frequency within some range.

   Parameters
   ----------
   a : array
       1D,2D or 3D Array : the array of timeseries to be filtered
   freq : float
       The cut-off frequency to set for the butter filter
   fr : float
       The framerate of the dataset
   N: int
       order of the butter filter

   Returns
   -------
   yf : array
       Filtered array of same shape as a
