在MATLAB环境下使用谱减法对语音信号进行增强，程序可以运行(In the MATLAB environment using spectral subtraction speech signal enhancement program can run)

这个是全部的matlab下的时频分布在故障诊断中的运用的代码(This is all the Matlab under the time-frequency distribution in fault diagnosis on the use of code)

一些数学建模用到的函数，代码，初学者可以试着编译看输出结果(some function to make mathmatic model)

In a series of papers in recent years new structures for coherent M-PSK (M-ary Phase Shift Keying) receivers were suggested. These include structures for carrier phase detectors for the carrier PLL (Phase Lock Loop), carrier PLL lock detectors, symbol timing error detectors, symbol synchronization PLL lock detectors, carrier and symbol PLL loop filters, and SNR (Signal to Noise Ratio) estimators

说明：  这是一个matlab程序，用于检测一组数据是否服从泊松分布。(This is a matlab program, used to detect whether the data obey a Poisson distribution.)

国外编写的一个QPSK仿真程序，给出了调制解调及误码分析(Foreign QPSK simulation program written in a given modulation and demodulation and error analysis)

这段程序是用来实现最优控制的，一段是关于倒立摆系统的，还有一个是一本书上的例题。比较适合初学者。(This procedure is used to achieve optimal control, a section is about the inverted pendulum system, there is a example on a book. More suitable for beginners.)

MATLAB程序封装成EXE文件，文章就如何实现这种转换做了详细的说明。(EXE file into a MATLAB program package, the article on how to achieve this conversion a detailed description.)

PROGRAM CALCULATES THE CHARACTERISTIC IMPEDANCE OF A MICROSTRIP LINE(USING THE FINITE DIFFERENCE METHOD THIS PROGRAM CALCULATES THE CHARACTERISTIC IMPEDANCE OF A MICROSTRIP LINE)

matlab提取图像质心和主轴，使用的是matlab图像处理工具箱函数(extraction matlab image centroid and the spindle, using matlab image processing toolbox functions)
