matlab

空时编码的一个matlab实现源程序，适合初学者。(Space-time coding to achieve a matlab source code, suitable for beginners.)

说明：  关于信号输入均匀量化器的信号幅度，用MATLAB实现量化过程(Uniform quantizer on the input signal amplitude, using MATLAB to quantify the process of achieving)

仿真产生简单的短路电压暂降信号,求小波系数模极大值(Simulation of a simple short-circuit voltage sag signal, find the modulus maxima of wavelet coefficients)

设计了谱减法，小波滤波法实现语音信号的增强的程序(Wavelet filtering through spectral subtraction speech enhancement method to achieve)

此程序为三维FDTD数值模拟，采用UPML边界(This program is three-dimensional FDTD simulation, using the boundary UPML)

支持向量机的程序，在机械故障诊断中可以用，可以运行(SVM program in mechanical fault diagnosis can be used, you can run)

MUSIC算法MATLAB程序 MUSIC算法MATLAB程序(MUSIC MATLAB)

matlab的getframe有时候并不能截取画出来的3D图像(而是截取出一个空坐标系).该程序用matlab调用windows的截图功能, 真正实现了原封不动的截图.(但是耗时会长一点). 使用时, 先把文件夹添加到matlab的路径下即可.文件夹中有两个功能略有不同的函数printScreen是截取整个屏幕, printFigure是截取整个屏幕后挖出当前的Figure窗口中的内容.(matlab does not intercept the getframe sometimes drawn 3D images (but the interception of an empty frame) The procedures used to call matlab windows screenshot function, truly untouched screenshot. (but a little time consuming president ) When using, first add a folder to the matlab' s path. folder has two functions is slightly different function printScreen intercept the entire screen, printFigure dug up the entire screen after interception current Figure window content.)

基于matlab的程序代码，关于图像匹配的不变矩的代码(Based on the matlab program code, code of invariant moment of image matching)
