[FieldTrip] Computing pca variables (i.e. Latent, and coefficient variables) after ft_componentanalysis

I have conducted a EEG experiement and am currently in a wedge. The PCA-function used in matlab ( i.e. pca() ) gives me the latent and coeff values that I want to use for further analysis. Sadly, I have cannot figure out how to perform a group level analysis using the matlab function and later "unmix" the group analysis to the subject level.
The a group analysis ft_componentanalysis function is easier to "unmix" thanks to its description of how to do so. However, I have not found a way to extract the latent and coefficient variables from the variables included in the comp-structure.
My question is:
Can you extract the latent and coefficient variables from the ft_componentanalysis results?
Is it possible to extract the subject level latent and coefficient variables using the matlab function pca() ?
