Matern32.power_spectral_density(omega)

The power spectral density for the Matern32 kernel is:

\[S(\boldsymbol\omega) = \frac{2^D \pi^{D/2} \Gamma\left(\frac{D+3}{2}\right) 3^{3/2}} {\frac{1}{2}\sqrt{\pi}} \prod_{i=1}^{D}\ell_{i} \left(3 + \sum_{i=1}^{D}\ell_{i}^2 \boldsymbol\omega_{i}^{2}\right)^{-\frac{D+3}{2}}\]
