It's not clear what is the output you want to obtain. Can you visualize it via an example and show?

Thank for the swift reply. I am not asking how to flip them around the x or the y axis. I am trying to find away to flip each maximum peak for eaxmple 180 degrees around itself, for it to become a minimum. Or to have the peak directed towards the other side.
