Can I get some guidance about how to access the computation of the inv and logdet in the marginal likelihood?

I need to modify the computation of the kernel inverse and and logdet in the Gaussian marginal likelihood with exact inference, but in the latest versions it became more obscure to me. Thank you!

Is this what you want to modify?
