余弦波是渐变的，当ωt+φ的取值变化量很小时，Y的变化量也是很微小的。余弦波的这一特性保证了嵌入水印后相邻字符灰度值差别不大，人眼无法识别，从而保证了水印的不可见性和图像质量。(Cosine wave is gradual, and when ωt+ φ values variation is very small, Y amount of change is very small. Cosine waves This feature ensures that watermarked gray value of adjacent character is not very different, the human eye does not recognize, thus ensuring the invisibility of watermark and image quality.)

大跨结构、高耸结构随机风荷载数值模拟，方便快捷、使用。(Span structures, the towering structure stochastic numerical simulation of wind loads, convenient to use.)

说明：  用于计算HURST指数的分形维数的MATLAB小程序，属于经典的。(HURST index used to calculate the fractal dimension of the MATLAB small procedures, are classic.)

初学CS，自己编了很多算法，试试发出来大家一起交流，基于CS的OMP算法(OMP algorithm based on CS)

实验三、四阶Runge-Kutta法求解初值问题，是我的实验报告。(The third experiment, fourth-order Runge-Kutta method to solve initial value problems, is my lab report.)

ofdm matlab code

说明：  EMD/EEMD的执行的模块,用于对信号进行分解，得到各阶IMF分量(EMD/EEMD the implementation of the module for the signal decomposed IMF components of the order)

一种多输入多输出支持向量回归机源代码，克服了传统支持向量机单输出的缺点(A multi-input multi-output support vector regression machine source code, to overcome the traditional single-output SVM shortcomings)

纠错编码原理课程中的一个作业MATLAB实现方式，汉明码(fsdgfsdgsdgsgsdgdfhfdjhfdg)

很好的模糊PID源代码，本人试验通过OK！(FuzzyPID)
