SUMMARY
The convolution of the functions exp(-a*norm(x)^2) and exp(-b*norm(x)^2) can be computed efficiently using the Fourier transform. Both functions are Gaussian, and their Fourier transforms remain Gaussian functions. The multiplication of these transforms simplifies the convolution process, allowing for straightforward computation using the properties of Gaussian transforms. The key to this method lies in applying the correct formula for Gaussian transforms.
