its a 3d MoM for RWG basis function and have a fun.

光伏pv特性图，在2010下可以直接仿真出波形(Photovoltaic pv diagram, can direct simulation waveform under 2010)

用于根据切削原理生成螺旋锥齿轮齿面散点。(Used to generate helical bevel gear tooth surface scatter according to the cutting principle.)

Adaptive Filter Matlab code

该程序由matlab编写功能为，应用模板的人眼定位(this program codec by matlab which have the function of eye location based on the application of model)

runga kutta numerical integration method forth order

基于梯度的亚像素配准算法的Matlab程序 (Gradient-based sub-pixel registration algorithm Matlab procedures)

该模型主要实现Chirp系统中Chirp信号的BOK调制，Chirp信号分为上扫频和下扫频信号，可以通过对正余弦信号进行BOK调制来产生。(This model mainly realize the BOK modulation Chirp Chirp signal in the system, under the Chirp signal is divided into the upper frequency sweep and frequency sweep signal, can pass to BOK is cosine signal modulation to produce. )

设计音频降噪算法，并用MATLAB仿真实现。 1）读入一段音频后添加噪声，必须包括两种不同的噪声，信噪比：0dB~10dB； 2）分别采用滑动平均滤波器，直接频域滤波，以及谱分析后设计滤波器滤波三种方法实现，并对比效果。 3）给出各种方案的设计依据、代码、频响曲线，以及输入输出对比图。(Audio noise reduction algorithm design, and use MATLAB Simulation. 1) Read after adding noise into an audio, it must include two different kinds of noise, SNR: 0dB ~ 10dB 2) respectively moving average filter directly in the frequency domain filtering, and the filter is designed to achieve three methods filter after spectral analysis and contrast. 3) Give the design basis, code, frequency response curve, and input and output comparison chart of the various programs.)
