Block LU decompostion of a matrix

给出五种常用小波基的时域和频域波形图及matlab代码。(Five commonly used wavelet basis is given time domain and frequency domain waveform and Matlab code.)

2 gaussian random variable generation and plotting using matlab code

是matlab产生一个高斯脉冲的程序，并且叠加了高斯噪声，可以画出输入与输出的图形，并且对其时延进行了估计(Is the matlab produce a gaussian pulse program, and stack the gaussian noise, can draw the input and output of the graphics, and the time delay were estimated )

generation of chaotic signals (logistic map)

high pass filter with FIR for education

用matlab写的图像离散余弦变换域的水印嵌入与提取以及攻击测试代码，稍加修改就可以移植到自己的程序中，很有用哦(Matlab write images using discrete cosine transform domain watermark embedding and extraction as well as attacks on the test code, slightly modified can be transplanted to their own program, very useful Oh)

说明：  一个有关核PCA的程序 主要用于模式识别和正交分解中(A nuclear PCA process is mainly used for pattern recognition and orthogonal decomposition)
