主成分分析代码， 可以用于图像压缩等等，也叫PCAH或者KL变换(PCA or K_L transfer)

Bilateral Filtering原始碼和測試圖片(Source code and test images Bilateral Filtering)

说明：  系统辨识与MATLAB仿真程序与剖析夹介绍了MATLAB应用入门方法，本程序是关于m序列的MATLAB程序。并提供具体程序予以分析(System identification and analysis of MATLAB simulation program with MATLAB Applications folder entry describes the method, the program is on the m sequence of MATLAB. And to provide specific procedures to analyze)

说明：  利用巴特沃斯（Butterworth）低通滤波器对受噪声干扰的图像进行平滑处理(Using Butterworth (Butterworth) low pass filter on the noise interference of the image smoothing)

说明：  灰色关联度的源代码，比较实用,用来进行关联度的计算 (this program Of Gray code, it is very practical.this program Of Gray code, it is very practical.this program Of Gray code, it is very practical.)

QPSK modulation with awgn channel

根据matlab的bvp4c函数的例子思想方法，求解特征值和特征函数，可以解变积分边界的问题，但是须给一个比较精确的初特征值。此为自编程序，已经标明注释。所附为bvp4c相关例子（此从matlab帮助文件节选）。(use the matlab solver bvp4c to obtain the both eigenvalues and eigenfunctions of BVPs, an exact initial eigenvalue is needed.)

数字水印在linux下面运行的代码，内有详细的注释说名(a watermarking program which can run under Linux. Attached with clear instructions.)
