旋转机械故障诊断与识别的方法频谱分析与功率谱分析

随机生成数【matlab例程】经典算法直接应用方便快捷(Random number generator convenient [] classical algorithm matlab routines directly applied)

当要隐藏信息时,在MATLAB的命令窗内输入命令: hide = myhide(carry,signal,x,y)； carry 用你的原始载体文件名代替，signal 用你所要隐藏的文件名代替 carry 和 signal 都必须是 *.* 的形式（注意不能省略单引号） x,y 是选取隐藏信息的位置坐标，在（x,y）和（y,x）处 生成的伪装载体文件名为hide.bmp 注意myhide.m文件，载体文件，隐藏文件都要在当前目录(current Directory)下 当要提取信息时，在MATLAB命令窗内输入命令： behidden = myinhide(carry,x,y)； carry 用你的伪装载体文件名代替,格式为 *.* （注意不要丢掉单引号） x,y 是选取隐藏信息的位置坐标，在（x,y）和（y,x）处，这必须和嵌入时所选位置一致。 提取出的信息文件名为behidden.bmp 同样，要注意behidden.m和伪装载体文件都要在当前目录(current Directory)下(when to hide information, in order MATLAB within a window orders : hide = myhide (carry, signal, x, y); Carry with you the original document name instead vector, signal used to hide your name in the paper and instead carry signal must be in the form of*.* ( not to single quotes omitted) x, y is to select the location of hidden information coordinates (x, y) and (y, x) The formation of camouflage vector document, entitled hide.bmp attention myhide.m documents, vector documents hidden all the documents in the current directory (current Directory) to retrieve information when, in order window MATLAB import order : behidden = myinhide (carry, x, y); carry using your camouflage vector file name instead, the format for*.* (take care not to lose a single quote) x, y election Hiding information )

说明：  自编：张贤达《数字信号处理》习题4.26的MATLAB程序。加入了一个GUI界面。 在MATLAB下运行MDSP。 要求MATLAB7以上版本，否则GUI无法运行(self : Automation, "Digital Signal Processing" Exercise 4.26 MATLAB. Adding a GUI interface. MATLAB running MDSP. MATLAB7 version of the above requirements, otherwise unable to run GUI)

粒子滤波的基本算法，源自N.J.Gordon的1993年的论文(It s the basic algorism of particle filter, extracting from the paper of N.J.Gordon in 1993)

DOA估计仿真，含有MUSIC,MVDR等算法(DOA simulation)

说明：  三种DOA估计的仿真图，分别是常规波束形成、MVDR和MUSIC。(Simulation Diagrams of Three DOA Estimations)

说明：  用遗传算法解决旅行商问题(附源代码)，遗传算法其实是一种求函数极值的随机搜索算法。(Solving the traveling salesman problem using genetic algorithms (with source code), genetic algorithm is a kind of extreme demand function of random search algorithm.)

matlab程序编译成独立exe文件 应用(matlab program compiled into an independent exe file)

用MATLAB实现的卡尔曼滤波，根据有用信号和干扰噪声的统计特性（自相关函数或功率谱），以线性最小均方误差（MSE），能最大程度的滤除干扰噪声，提取有用信号。(Kalman filter using MATLAB, based on the statistical properties of the useful signal and interference noise (autocorrelation function or power spectrum), linear minimum mean square error (MSE), filter out noise interference to the greatest extent, to extract the useful signal.)
