LMI 控制工具箱，采用内点法的 LMI 求解器，这些求解器比经典的凸优化算法速度有了显著提高。另方方面，它采用了有效的LMI结构化表示，在求解和计算领域做出了重大贡献。(The LMI control toolbox uses the LMI algorithm of the interior point method. These solvers have significantly improved the speed of the classical convex optimization algorithm. On the other hand, It uses effective LMI structured representation, and has made significant contributions in solving and computing fields.)
