悬臂梁频率方程计算；将完整模型与损伤模型进行对比分析(Beam frequency equation to the full model were compared with the damage model)

说明：  该程序是锁相环的MATLAB的简单实现程序，从中可以看到锁相环的基本功能的实现。(This program is a simple phase locked loop of MATLAB implement programs, from which you can see the basic function of phase-locked loop of implementation.)

超声2维成像，运用DAS算法，算法比较简单，可供初学者看看。(2-dimensional ultrasound imaging, the use of DAS algorithm, the algorithm is relatively simple for beginners to see.)

主要是掺钇光纤的速率方程，可以实现图形化。(Yttrium-doped fiber is mainly the rate equation can be achieved graphically.)

ofdm系统matlab仿真研究，结合书本觉得很有用。(Simulation of the system matlab OFDM, combine the book feel useful.)

double_pendulum_init initial for the pendulum

说明：  就是用MATLAB绘制,一个颜色编码的混淆矩阵。(MATLAB is used to draw a color coded confusion matrix.)

that is so important code of matlab in back propagation !

This MATLAB implementation computes a correspondence between two shapes based on ant colony optimization (ACO). The input shapes can be either two 2D contours (open or closed) or two arbitrary sets of 2D points. The algorithm is described in detail in:
