[SciPy-User] variable smoothing kernel
Sat Mar 26 20:09:34 CDT 2011
If I understand correctly, you want a filter that varies on "time".
This non-linearity will cause it to be inherently more complicated to
calculate than a normal linear time-invariant filter.
I second Christopher's suggestion, try Cython out, it's great for this
kind of thing. Or perhaps scipy.weave.
