简易四则运算计算器，使用时需将.m和.fig文件放到matlab工作目录下（本人使用的是R2013，放到bin文件夹即可，其他版本放到对应文件夹，有的是work文件夹），然后在命令窗口输入.m文件的文件名，即可显示一个简易计算器界面。有0-9九个数字供点击输入数，有重置和正负号按钮，界面简洁，功能耐用(Simple arithmetic calculator should be used with the. M and. Fig file into matlab working directory (I use the R2013, into the bin folder to the other versions into the corresponding folder, some work folder) , and then in the command window. filenames m file to display a simple calculator interface. 0-9 nine figures for the number of click enter, and the sign has reset button, the interface is simple, functional and durable)

振动信号时域处理办法，包括低通、带通滤波和频域积分法(Time-domain vibration signal processing options, including low-pass, band-pass filtering and frequency-domain integral method)

matlab自编程序，实现读取txt文件的一些数学分析：如标准化方法等(self matlab program to read txt files to achieve some of the mathematical analysis: such as a standardized method)

升cosine窗加权的波束方向图：N=11(Raised cosine weighting function)

该源码用于分析信号的时频特性，wigner-ville分布，单信号以及两个信号间的正交wigner-ville分布(wigner-ville distribution)
