Create the Jacobian and call MATLAB's eig.
Or what's the difficulty you encounter ?

Usually the Jacobian varies with time. When do you want to form it and compute the eigenvalues ? Once at the start and at the end of the simulation ?
In any case: You will have to write your own code to calculate the Jacobian.
