Can matlab perform perturbation & linearization on a state average model? (power electronics are of specific interest, but field is probably irrelevant)

As the title says, I was wondering if there is a tool in Matlab that performs perturb and linearization on state matrices. An example matrix is shown in the photo

I did a quick search and found nothing, hence I'm trying the community.

Depending on how you are going to model your averaged value model. For instance, you can model the average value model using 'ss' (https://www.mathworks.com/help/control/ref/ss.html). You can then analyze this state-space model.

Alternatively, you can model the power electronics circuit in Simulink with higher fidelity. Based on the Simulink model, you can then use the linearization and frequency response estimation approaches from Simulink Control Design: https://www.mathworks.com/help/slcontrol/ug/linearize-simulink-model.html
