粒子群优化算法。这个程序就是最基本的粒子群优化算法程序，用Matlab实现，非常简单。只有几十行代码。(Particle Swarm Optimization. This program is the most basic particle swarm optimization program using Matlab, very simple. Only a few dozen lines of code.)

基于频率切片小波变换预处理，此方法适用于盲信号分离的预处理，方法有很多优点。(Based on the frequency slice wavelet transform preconditioning, this method is suitable for the pretreatment of blind signal separation, the method has many advantages.)

径向基神经网络Matlab编程，包含4个分厂不错的Matlab程序，读者可以下载运行一下看看。(Radial Basis Function Neural Networks Matlab programming, including 4 branch good Matlab program, readers can download to run about to see.)

程式用matlab工具程式編輯實現了小波變換進行圖像壓縮,並且顯示壓縮前後的圖像。 代碼很簡明清晰,適合初學者研究和學習(Editing utility program to achieve with the matlab wavelet transform image compression, and displays the image before and after compression. The code is simple and clear, suitable for beginners research and study)

数字信号的处理，正弦函数与余弦函数的结合(digital signal prozessing sin cos function)

noise reduction method

BBBCF 宇宙大爆炸优化算法的matlab源码,一种相对来说比较新的优化方法，用于求解最优解问题(BBBCF iterates one iteration a population according to the rules of Big-Bang Big Crunch method. It overwrites new population over the previous one. As the number of iterations grow, it searches new candidates in alimited search space.)

EM算法，基于期望最大化原则进行密度估计(EM algorithm, based on the expectation maximization of the principle of density estimation)

apply a lowpass filter to a watermarked audio signal to test the robustness input : vector representing the watermarked audio file output : vector representing the watermarked audio file corrupted by a highpass filter
