Since 2016, I put all my code into github: link.
You need CVX to run the following code examples:
Matlab code for Y. Yuan, M. Li and C. J. Tomlin, On the Powerball method. download
Matlab code for Y. Yuan, Y. Nakahira and C. Tomlin, On identification of parameterized switched linear systems. download
Matlab code for W.Pan, Y. Yuan*, J. Goncalves and G.-B. Stan, A Sparse Bayesian Approach to the Identification of Nonlinear State-Space Systems. Download
