My understanding of the root of the problem is that you end up with
doing many evaluations of sinc. If this is so, one suggestion is to go
with pre-computed filters. For example, if you are resampling from 9
points to 10, essentially you're trying to go from a function that is
defined on points 0,

Hi,
I have to send this request second time since my first message contains the
attached data file which is too big and was blocked by the system. So this time
I will not attach the data file.
I have converted a matlab function to python using numpy. both matlab and
python run slow. I know
