Extracting system of ODEs from Cantera using Matlab

I am working with the Cantera package in Matlab. Specifically, I am using the conhp.m code avaliable on https://cantera.org/examples/matlab/conhp.m.html

This Matlab function, according to the description, evaluates the system of ordinary differential equations for an adiabatic, constant-pressure, zero-dimensional reactor.

I am simply interested in extracting the system of ODEs that it uses. Assuming I use "gas = GRI30" as input, which has 53-species and 325-reactions, how do I get the system of embedded equations of the form y' = f(y)?

Any help would be greatly appreciated. Thanks!

Any ideas or general strategies to go about this?
