  1. Axes (1,0) means that we used rfft with axes (0,1), and axes (1,0) means that we used rfft with axes (1,0)
  2. Differnet axes order implies different results as the the first axes is associated with whole dimension, yet the second axes is associated with half of the dimension. For example rfft(A(time,lon),axes=(1,0)) result in time/2,lon , yet if we use axes(0,1) we get time, lon/2 or backward .. not sure from the order
