这是一个单摆模型的分岔行为的分岔图，是我珍藏的，供大家参考。 (This is a simple pendulum model of the bifurcation behavior of the bifurcation diagram, is my collection, for your reference.)

单基地正侧视条带式SAR仿真，采用的是RD算法(One base is side view of band SAR, RD Algorithm Simulation)

设计一个低通数字滤波器，满足如下设计指标： 通带截止频率：0.2pi，通带波动：1dB 阻带截止频率：0.3pi，阻带衰减：15dB 要求：分别采用巴特沃斯、切比雪夫Ⅰ型、切比雪夫Ⅱ型和椭圆滤波器原型进行设 计，比较各种设计的阶数、实际阻带衰减，分析实验结果 (Design a low pass digital filters that meet the following design specifications: passband cutoff frequency: 0.2pi, pass-band fluctuations: 1dB stopband cutoff frequency: 0.3pi, stop-band attenuation: 15dB requirements: respectively Butterworth, Chebyshev Ⅰ, Ⅱ and Chebyshev prototype elliptic filter design, comparing the order of the design, the actual stop-band attenuation, analysis of experimental results)

信号处理的Fast ICA实现进行快速独立分量分析(Fast ICA signal processing to achieve fast independent component analysis)

本实验主要是学会利用matlab软件，在用编程语言实现单样本均值和方差的区间估计的过程中，调用matlab工具中的数学函数来完成计算功能，并绘制出样本均值概率分布图和样本方差分布图。(This experiment is to learn to use matlab software, a programming language to achieve a single sample interval estimation of the mean and variance of the process, call matlab tool to calculate mathematical functions to perform the function, and draw out the probability distribution of the sample mean and sample variance distribution Figure.)

双馈电机 控制 波形很好 参数调节的很正确 得出了好的控制效果(Double-fed motor control waveform parameter adjustment is very well drawn correctly good control effect)

说明：  子波模拟的程序，对于用信号处理方法处理勘探地震信号的同学们有一些帮助(Sub-wave simulation of the process, with the signal processing method for exploration seismic signal processing students have some help)

该程序能够将matlab中绘制的三维图形，动态化，并最终生成gif文件，原理是使用了getframe()函数，获取几帧图像，再保存为gif文件 (The program can draw matlab in the three-dimensional graphics, dynamic, and ultimately generate the gif file, the principle is the use of getframe () function, to obtain a few frames, and then saved as a gif file)

锁相环模型，可以用于很多种控制中，应用很普遍(PLL model, can be used for very many kinds of control, the application is very common)

说明：  环境：matlab 算法：Kmeans 功能：对iris数据进行分类(Classification of iris data by kmeans algorithm)
