This function used to calculate PCA of image.

在已知光纤在特定波长处的折射率的情况下，该程序可以迅速计算对应模式的色散值(Optical fiber have been known at a particular wavelength of refractive index of the case, the program can quickly calculate the dispersion value of the corresponding mode)

test BPSK ofdm add awgn ber

This is a code to generate the bifurcation diagram for logistic map.

This function performs the ASK,BPSK and 8PSK modulations.

用matlab画正玄函数的图形以及变化，包括FFT 加白噪声。(Matlab draw with the graphics functions are mysterious as well as the changes, including FFT plus white noise.)

this file implements the algorithm of DWT and DCT for image watermarking in combination.

MATLAB编写的误差反向传播（BP）神经网络简单分类器。(MATLAB prepared by error back-propagation [BP] neural network classifier easy.)

该实例主要功能： 1、演示了GUI界面的布局和效果； 2、演示了togglebutton、pushbutton对simulink模块参数的设置方法； 3、演示了Edit text 和slider的联合使用，及利用edit text 和slider 对simulink 参数的动态修改； 4、演示了simulink参数在GUI上的显示和更显； 5、语句进行了注释，为便于编译没用中文，大家凑或者看吧！(The main functions of examples: 1, presentation of the layout of the GUI interface and effectiveness 2, demonstrated togglebutton, pushbutton module to simulink Ways parameters 3, Edit text and to demonstrate the joint use of slider, and the use of the slider and edit text simulink dynamic parameters modified 4, demonstrated on simulink parameter GUI at the display and more 5, statement to the Notes, in order to facilitate the compiler no English, or U.S. Check it out together!)

说明：  产生雷达中常用的sinc函数和chirp函数，以及均匀分布和高斯分布的白噪声(Commonly used in radar have sinc function and the chirp function, as well as the uniform distribution and Gaussian distribution white noise)
