小波变换下的信噪比提高,运行结果是3张图，两段语音，效果较为明显(Improved SNR under the wavelet transform)

主要介绍了舰船辐射噪声的生成，包括宽带连续谱和线谱的建模仿真，得到了不错的效果(Mainly introduces the generation of ship radiated noise, modeling and simulation, including broadband line spectrum and continuous spectrum, obtained good results )

time series In this example we will use a synthetic data set. To create our synthetic data we will make our unit of time 1000 years = 1 ky and sample a 500,000 year record in 2 ky increments. We first create a vector containing the times:

人工鱼群算法源代码,最基本的代码。可以很好的理解人工鱼群算法(Afsa is old code)
