[Numpy-discussion] How to make scipy.interpolate give a an extrapolated result beyond the input range?

2010-04-30 Thread Salim, Fadhley (CA-CIB)
I'm trying to port a program which currently uses a hand-rolled C++ interpolator (developed by a mathematician colleage) over to use the interpolators provided by scipy. I'd like to use or wrap the scipy interpolator so that it's behavior is as close as possible behavior to our old interpolator.
