说明：  用朴素贝叶斯方法实现了Iris数据的分类，还附了实验报告(Bayesian methods implemented with the Iris data classification, but also with the experimental report)

Matlab循环定义变量，可以定义任意多个变量，matlab字符串数组的创建(Matlab loop defined variables, you can define any number of variables, matlab creation of an array of strings)

traveling saleman problem的代码(traveling saleman problem code)

说明：  Beamforming Example problem using Minimum Variance Distortionless Response (MVDR) approach with a Uniform Linear Array (ULA) of five elements and interference and noise.

仿真程序：首先需要用一个随机发生器产生（0.1）内的均匀随机数，然后再将该序列映射到对应的幅度电平｛Am｝。然后将这个范围再分成4个相等的区间，这些子区间分别对应于4个信号比特的符号00，01，10，11。检测器观察到r=Am+n，并且计算r和4种可能传输的信号幅度之间的距离，它的输出Bm就是相应于最小距离的信号电平。Bm与真正的的传输信号幅度比较，差错计数器用来对检测器产生的差错计数。(Simulation program: first need to use a random generator (0.1) the uniform random number, then the sequence is mapped to the corresponding amplitude level {Am}. Then this range has been divided into four equal intervals, these sub-intervals corresponding to four signal bits of the symbol 00,01,10,11. Detector observed r = Am+ n, and calculate r and 4 possible transmission distance between the signal amplitude, its output corresponding to the minimum distance Bm is the signal level. Bm and the real rate of transmission of the signal comparison, error detection counter is used to generate the error count.)

通信系统工具箱 4.2 是通信系统仿真必备的工具 很全 分方便(Communications System Toolbox 4.2 is an essential tool for communication system simulation is the whole convenience )

MATLAB行情软件MatlabTraderGUI 1.完成了日线、周线、月线等不同周期的展示。 2.完成了MACD,BOLL,RSI,W&R,OBV,DMI,PVT等技术指标的展示。左上的两个均线的长度参数可以动态修改展示。 3.增加了展示范围的调整。(相当于普通行情软件的上下键) 4.增加了水平的slider用来滚动展示K线。（相当于普通行情软件的左右键） 5.拖动水平的slider，三个axes可以同步移动（拖动）。 6.按下鼠标左键，可以展示十字光标，右面的table可以展示十字光标处的 开高低收量。 7.在每个axes都增加了右键，可以进行图片另存为。 8.老规矩，Mcode我打包一并放出来，想用的拿去，可以直接改源代码，作为学习GUI是个不错的范例，我为人人，人人为(MATLAB software market MatlabTraderGUI 1 completed the daily, weekly different cycles, such as monthly show. 2 complete shows MACD, BOLL, RSI, W & R, OBV, DMI, PVT and other technical indicators. The average length of the upper-left of the two parameters can be modified dynamically show. 3 shows an increase adjustment range. (Equivalent to ordinary market down key software) 4. The slider to increase the level of K-line scrolling display. (Equivalent to about key common market software) 5 Drag the horizontal slider, three axes can be synchronized to move (drag). 6 Press the left mouse button, you can display the crosshairs, the right of the table can show opened at the level of the yield of the crosshairs. 7 have increased in each of the axes right, the picture can be saved as. 8 old rules, Mcode I packed together put out, want to take it to use, you can directly change the source code as a learning GUI is a good example, one for all, all for one )

伪Wigner-Ville分布对实验采集外圈故障的振动信号进行分析，看出信号存在故障引起的冲击分量(The pseudo Wigner-Ville distribution is analyzed to the vibration signal of the outer ring fault, and the impact component caused by the signal is found.)
