根据梁的弯曲振动方程解析求解梁的模态。算法清晰简便！清晰！很好用！(Based on the modal bending vibration equation analytic solution of beam. Algorithm is simple and clear! Clear! Very good use!)

OFDM 系统信噪比估计，matlab源代码(OFDM system, SNR estimation, matlab source code)

This file has a function for LDA

超声图像实时消噪实验程序，还没有完成，或许有很大帮助(Real-time ultrasound image denoising experimental procedure, has not yet been completed, then it might be very helpful)

一个基于matlab的有限元分析程序，用三角形单元对二位有限元问题进行分析(A matlab based on the finite element analysis program, two finite element analysis using triangular elements)

说明：  通过MATLAB绘制出正弦函数、余弦函数及指数函数的曲线，并加以标注(MATLAB curve drawn by a sine function, cosine, and exponential functions, and to be marked)

仿真实现接收信号并进行数字下变频处理，并进行了滤波，实现了降采样率的处理过程(The received signal is simulated and processed by digital down-conversion, and filtered. The process of reducing sampling rate is realized.)

关于支持向量的简单分类和多分类与优化，还有不变矩的编程(Support vector classification of simple and multiple classification and optimization, there are moment invariants programming)

天波超视距雷达系统仿真(多波束形成)，代码在paper中，而且给出了详细的说明，能够更好理解田博超市距雷达的工作原理(Horizon radar system simulation (multi-beam forming), the code in the paper, but also gives a detailed description, to better understand the field Bo supermarket works from the radar)
