应用bp神经网络进行分类的实例，很简单适合初学者。(Application of bp neural network to classify instances, is very simple for beginners.)

本程序是分析不同结构树的峰均功率比的仿真程序(This procedure is to analyze the structure of trees of different peak to average power ratio of the simulation program)

A Quadrotor simulation that is performed in MATLAB and SIMULINK

matlab编写的模拟滤波器的设计，经运行完全正确！(matlab filter design simulation prepared by running completely correct!)

this file to calculate the cp/lambda for different types of pitch angles. the selected wind speed range where the rated wind speed is 9 m/s and beta angle is zero the maximum value of beta is 45 but in the simulation it maximum value will not be more than 36 degree

有记忆预失真处理程序，可以实现对PA转换下饱和失真的处理(Predistortion with memory processes can be achieved under the PA saturation distortion conversion process)

要求设计一个基于颜色直方图的图像检索系统。该系统能够实现对图像的检索功能，例如，在一万幅图像中搜索出与检索图像相似的图像，依相似程度的大小显示出来。最后用查全率和查准率对系统进行评估。(To design a color histogram based image retrieval system. The system can realize the image search function, for example, a square image search and retrieval of an image similar to the image size according to the degree of similarity is displayed. Finally, recall and precision to evaluate the system.)

说明：  最优化算法，使用信赖域法（LM）求解无约束问题。可以实现画出三维图像，通过修改初始点，得到迭代次数和函数值(Optimization algorithm, using LM method to solve unconstrained problems. Three dimensional images can be drawn, and the number of iterations and function values can be obtained by modifying the initial points.)

信道测试。信号保存为.wav格式，测试信道的平稳性能。(Channel test)
