DS证据理论用于信息融合。很多学科都可能用到。(construction of the Membership function. Many disciplines may be used, in particular information class students)

time frequency analysis

信号的相关性是信号本身很重要的性质，本程序就是求随机信号的自相关性。(Signal is the relevance of the signal itself is very important properties, this procedure is for the random signals between autocorrelation. )

超声仿真的代码，matlab的，对于阵元的发射接收的例子，是很好的学习资料。改代码依附于丹麦理工的fieldtwo，可以参考user guide进行仿真。里面是文本格式的，打开转成.m文件即可(Of ultrasound simulation code, matlab example for the launch of the array element receives a good learning materials. Change the code attached to Danish Polytechnic fieldtwo, can refer to the user guide Simulation)

电力电子电机控制MATLAB仿真模型，包括矢量控制盒直接转矩控制，以及变流变频等(Power electronic motor control MATLAB simulation model, including vector control box direct torque control, as well as inverter variable frequency)

该代码实现了以2为因子的图像升采样和降采样功能。 降采样包括使用平滑滤波器(with using the averaging filter)和不使用平滑滤波器(without using the averaging filter)两种方法。 升采样包括像素点直接复制(pixel replication method)和线性插值(bilinear interpolatoin method)两种方法。 降采样方法和升采样方法共有4种组合。程序运行后，给出了一个原始图片和四个结果图片。 图片1.原始图片。 图片2.平滑滤波器降采样&像素点直接复制升采样。 图片3.平滑滤波器降采样&线性插值升采样。 图片4.不使用平滑滤波器降采样&像素点直接复制升采样。 图片5.不使用平滑滤波器降采样&线性插值升采样。 (The code to achieve a 2-factor image upsampling and downsampling function. Down-sampling (with using the averaging filter) and do not use smoothing filter (without using the averaging filter) are two ways to use the smoothing filter. Upsampling including the pixels copied directly (pixel replication method) and linear interpolation (bilinear interpolatoin method) two methods. Down-sampling method and liters a total of four combinations of sampling methods. The program is running, it shows a picture of an original picture and four results. Picture 1 original picture.

运行程序得到微分方程中x1随参数omega变化的分岔图。omega的范围选取可以调节。(Run the program to be differential equations with parameters x1 bifurcation diagram omega changes. omega scope of selection can be adjusted.)

在论坛上经常有朋友求关于信号上下包络的程序。 本程序为本人编写的一个matlab程序。(at the forum frequently for friends on the next signal envelope procedures. The procedures for the preparation of the one I Matlab procedures.)

Edge detection refers to the process of identifying and locating sharp discontinuities in an image. The discontinuities are abrupt changes in pixel intensity which characterize boundaries of objects in a scene.

一套完整的8-PSK调制解调的程序，对学习通信原理的初学者很有帮助。(A GOOD RESOURCE FOR STUDING MODULATION AND DEMODULATION )
