[Numpy-discussion] A faster median (Wirth's method)

2009-08-31 Thread Sturla Molden
We recently has a discussion regarding an optimization of NumPy's median to average O(n) complexity. After some searching, I found out there is a selection algorithm competitive in speed with Hoare's quick select. It has the advantage of being a lot simpler to implement. In plain Python:
