定义surface distance， matlab 代码，可以运行，计算两个曲面 球面之间的距离(surface ellipsoid distance calculation )

The given code contain Matlab code for the adaptive thresholding, This technique is more efficient than the normal gray level thresholding

清华老校歌，直接运行播放清华大学的老校歌，主函数是matlab中的sound,文件名和函数名要一致(The song of Tsinghua University)

控制理论算法在采用状态反馈对目标进行控制时，往往忽略了时滞的存在。时滞往往存在于真实的系统中，而忽略时滞所设计的控制器在复杂的系统中可能会失效。本算法基于李雅普诺夫稳定性理论，以LMI的方式给出时滞系统的稳定性分析判据。(Time delay is widely existed in many engineering contrl systems whiile in many contrl theory and algothms time delay is ignored. This algorithm is given to analysis the stability of close- loop feedback time delay systems. And classical examples are given to demanstrate the effectiveness of this method.)
