Hi everyone, I am proposing to add the the two following functions to numpy/lib/twodim_base.py:
sum_angle() computes the sum of a 2-d array along an angled axis sum_polar() computes the sum of a 2-d array along radial lines or along azimuthal circles https://github.com/numpy/numpy/pull/230 Comments? When I was looking for a solution to these problems of calculating special sums of 2-d arrays I could not find anything and it took me a while to figure out a (hopefully) useful and consistent algorithm. I can see how one would extend these to higher dimensions but that would preclude using bincount() to do the heavy lifting. Looking at some other functions, the doctests might need to be split into real examples and unittests.
