I have a 2D Float64 array, and I would like to Gaussian filter it. I'm familiar with the Mathematica equivalent, which is `GaussianFilter[array, sigma]`. Is there an equivalent in Julia?
I know there is a fast Gaussian filter implemented in the Images package, but it (as best I can tell) only works for images, not numerical arrays. In the Standard Library, there is conv2, but it uses FFT methods, which are slow and unnecessary.
