说明：  瞬时相位法线性调频信号瞬时频率提取技术研究matlab程序并附有一篇找到的论文(a matlab program Instantaneous Phase Linear FM signal instantaneous frequency extraction technique together with a paper)

说明：  齿轮动力学分析，计算duffing系统下特性，振动情况等(To solve the nonlinear problem of gear dynamics analysis, the calculation of duffing system characteristics, vibration, and so on)

说明：  The program can detect the phase difference between one Sinoid signal with another sinoid signal and can generate a new signal of same phase

4Cyclist problem simulation model Four cyclists are at the desert. Each of them starts from a different location and tries to reach the other ones. Cyclist 1 goes straight to cyclist 2, cyclist 2 straight towards cyclist 3 etc. such that finally the cyclist 4 goes straight towards cyclist 1. Form the equations, build a Simulink-model and find out the meeting point of the cyclists by simulating the system with the following initial values:
