- 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)
- 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
