实现了用LSB嵌入水印，还有两种水印分析方法：X2和信息量分析法(Achieved using LSB embedding the watermark, there are two kinds of watermarks analysis methods: X2 and the amount of information analysis)

在matlab环境下绘制评估边缘检测性能的ROC曲线。(This ROC curve is a method to evaluate the performance of edge detection algorithms.)

说明：  BCH 编解码的MATLAB 实现。BCH码是一类重要而有效的纠正多个随机错误的循环码，由于该码具有严格的代数结构，所以是到目前为止研究得最为详尽、应用最为广泛的一类码，已有多种译码算法。(BCH codec of MATLAB. BCH is a kind of important and effective redress the wrong number of random cyclic code, as the code strictly algebraic structure, it is so far the most detailed study in, the most widely used type of a code has a variety of decoding algorithm.)

Image Warping source code for MATLAB

k-means无监督机器学习聚类算法，使得同聚类中的记录欧式距离最小。(K-means machine learning method without instruction, minilizing the distances of records in each clusters the. )

说明：  用途：用定步长高斯就积公式求函数的积分 magsint(q)

说明：  包括matlab所有常用的函数 自己一个一个整理的，还挺好用的(Including all commonly used matlab functions themselves one by one finishing, quite useful)

现代信号处理：取不同长度的窗函数，分别求x(n)的离散短时傅里叶变换，并进行信号重构(Modern Signal Processing: Take the window function of different lengths, respectively, find x (n) of the discrete time Fourier transform and signal reconstruction)

写了著名的最小均方准则下的自适应算法，在matlab环境下运行(Wrote a well-known least mean square criterion of the adaptive algorithm, running in matlab environment)
