自己编写的绘图相关的函数，对于初学者很有用！！！(Graphics Related)

说明：  用模式传输法计算多模干涉波导的模场传输,多模干涉波导参数可调(calculate the beam propagation inside MMI using mode propagation method)

二相编码信号的三次相位函数的matlab程序，自己编的，希望大家批评指正(cubic phase function of BPSK)

利用Gabor滤波器进行特征提取，在信号与图像处理领域有着广泛的应用。参考文献“Efficient Computation of Gabor Features”(Gabor fi lter responses are widely and successfully used as general purpose features in many computer vision tasks, such as in texture segmentation, face detection and recognition, and iris recognition.)

自己编写的图像增强程序，提供MATLAB的源码下载和实例，适合初学者进行学习。(I have written image enhancement procedures, and provide examples of MATLAB source code download, suitable for beginners to learn.)

说明：  本文件包含som-bp串联神经网络的代码和数据，可用来做数据拟合，改成你自己的数据即可(This file contains the code and data for the som-bp series neural network, which can be used for data fitting and changed to your own data)

DES function for the encryption of DES,use matlab to make it possible,first input in the function is plaintext ,second one is key,and last is to choose encrypt or decrypt

import dalvik.annotation.TestTargetClass for Andriod.
