[SciPy-user] Fast Gauss Transform

While fiddling with new code to compute kde, I noticed that gaussian_kde has
an unexpected behavior for 1D arrays.
For instance :
x = rand(1000)
g = gaussian_kde(x)
returns the same value no matter what z is. The problem disappears for
multidimensional data. The dot product (self.inv_cov, diff) seems to be
causing the problem, doing the product only for the first element of diff
and returning zeros for the rest. I guess this is not the intended behavior
