方程求根，有很多方法，包括常用的很多M文件，很实用(find the roots)

数字调制解调的MATLAB仿，包括4qam,8qam，16qam,64qam的调制和解调程序(Digital modem imitation of MATLAB, including 4qam, 8qam, 16qam, 64qam process of modulation and demodulation)

A speech signal filterbank, using melscale frequency and framebanking.( 1. For speech signal can be represented as a discrete sequence of frames (or feature vectors) that can be used as the input to a speech recogniser. Important ideas and techniques that are used in the assignment are the design of a (Mel frequency scale) audio filterbank, , windowing of a continuous audio signal, spectrum analysis of the signal, filtering as multiplication in the frequency domain, the visual representation of a speech signal as a spectrogram, appreciation of the acoustic variability in real speech utterances. 2. To gain a deeper knowledge of the application of MATLAB programming to audio signal processing. 3. To gain practice in the art of writing a formal report: structure, content, style, use of diagrams, presentation etc. etc. )

说明：  卡尔曼滤波matlab源程序，对于过程控制及航空航天航海等有重要作用(Kalman filter matlab source, for process control and aerospace navigation and so plays an important role)

正弦sin映射，要学习混沌的可以了解下，还有pdf曲线(Sine mapping with pdf curve, learning chaos can understand)

CSO算法，用matlab编写，直观画图显示结果。带五个基本测试函数(CSO algorithm, using MATLAB to prepare, intuitive drawing display results. With five basic test functions)

城市切换功能,点击城市可以弹出其他城市进行切换(the demo is to change city)

说明：  这是利用改进的kalman滤波来处理GPS信号，通过与传统的kalman滤波比较得到较好的效果。直接解压，就可以导入work里运行。(This is the improved GPS kalman filter to process the signal, by comparison with the traditional kalman filter get better results. Direct decompression to work can be imported to run. )

a code source for 3D display

数字调制的经典书籍，涵盖各种调制方式，通过本书能对数字调制有个全面的了解(Digital modulation of the classic books, covering a variety of modulation)
