[SciPy-user] Fast Gauss Transform

Hi,

Is anyone aware of a piece of code for N-D Fast Gauss Transform (in python,
C or fortran) ? The only codes I could find were for one dimensional cases
(Strain's), or in C++ (Yang) but relied on the matlab mex library. I used
stats.gaussian_kde but it proves too slow for large arrays (4 x 100 000)

Thanks,

David
