Lyapunov stability analysis procedure in MATLAB version 2010a

Dear Sir How are you Hope that you are fine and well. I have a simulink model and I achieved to linearize the model through simulink control design but actually I do not know how to check the stability of the control loop by using the Lyapunov stability theorem in Matlab. Would you kindly, if possible help me on this matter, Please. Thank you

Lyapunov stability for linear models simply means that all real parts of eigenvalues are less than zero. For a linear system sys you can quickly check this by using command isstable.
