Code your function so that it works well for 2D arrays (using axis=-1 and co), then use a decorator on it so that if you pass it an N-d array, it transforms it in a 2D array, passes it to the decorator, then transforms the output back to the right shape. The idea is quite theoretical, and I have never gotten to implement it, because when I was facing similar problems, it didn't come to my mind, but I think it can work in a very general way.
