说明：  多项式曲线拟合其中, x, y为已知数据点向量, 分别表示横,纵坐标, m为拟合多项式的次数, 结果返回m次拟合多项式系数, 从高次到低次存放在向量p中. (Polynomial curve fitting where, x, y as the vector of known data points, respectively, horizontal and vertical coordinates, m is the number of polynomial fitting, the results of m-fit polynomial coefficients returned from higher to Low times stored in the vector p,.)

自己编写的，使用morlet复指数小波，进行连续小波变换的程序。能帮助理解小波变换的算法。(I have written using complex exponential morlet wavelets, continuous wavelet transform performed procedures. To help understand the algorithm based on wavelet transform.)

使用大量的有限元法求解偏微分方程，验证可用，给出接收信号眼图及系统仿真误码率，一些自适应信号处理的算法，主要是基于mtlab的程序，多元数据分析的主分量分析投影，这个有中文注释，看得明白。( Using a large number of finite element method to solve partial differential equations, Verification is available, The received signal is given eye and BER simulation systems, Some adaptive signal processing algorithms, Mainly based on the mtlab procedures, Principal component analysis of multivariate data analysis projection, The Chinese have a comment, understand it.)

使用matalb软件，利用递推阻尼最小二乘法进行参数辨识，并改变噪声的强度，即 a*ξ(t)（0<a<1），分析、比较一般递推最小二乘和递推阻尼最小二乘方法的优缺点 ；(Use matalb software, the use of recursive damped least square method for parameter identification, and change the intensity of noise, that is a* ξ (t) (0 <a<1），分析、比较一般递推最小二乘和递推阻尼最小二乘方法的优缺点 ；)

This code simulate MRC receiver in wireless network for different SNR. this program is for MATLAB.

基于MATLAB的各种优化算法，里面含多种利用MATLAB进行的算法，简单实用(MATLAB various optimization algorithms, which contain a variety of algorithms using MATLAB, simple and practical)

使用矩量法计算微带天线的特征阻抗，用户需自行更改其中的天线的几何尺寸和工作频点．(Calculated using the method of moments microstrip antenna characteristic impedance, the user need to change one of the antenna geometry and frequency.)

说明：  euler格式前进、后退和改进的格式，并在一个程序中(euler)

说明：  挠性转子的平衡原理是建立在弹性轴（梁）横向振动理论的基础上，其动平衡原理为：挠性转子在任意转速下回转时所呈现的动挠度曲线，是无穷多阶振型组成的空间曲线，其前三阶振型是主要成分，振幅较大，其他高阶振型成分振幅很小，可以忽略不计。(Flexible rotor balancing principle is based on the elastic axis (beam) on the basis of transverse vibration theory, the balancing principle is: flexible rotor turning at any speed when the deflection curve presented is composed of infinite number of vibration modes space curve, the first three modes is the main component, the larger the amplitude, the amplitude of the other components of higher modes is very small, can be ignored.)
