舰船辐射噪声的产生，可利用其模拟舰船辐射噪声，从而达到定位等目的(generation of Ship radiated noise)

说明：  拉普拉斯高斯算子 拉普拉斯—高斯算子（Laplacian of Gaussian算子，通常缩写为log算子）是一种二阶微分算子，将在边缘处产生一个陡峭的零交叉。(Laplace Gaussian operator Laplace- Gaussian operator (Laplacian of Gaussian operator, often abbreviated as log operator) is a second-order differential operator, will be generated at the edge of a steep zero crossing.)

這個檔案裡面的matlab的m函數，產生有效的都普勒fd隨機相關的瑞利衰減包絡，可以輸入你想要的doppler ferquecy和sampling ferquecy (This file inside the matlab m-function, effective Doppler fd related Rayleigh random attenuation envelope, you can enter your desired doppler ferquecy and sampling ferquecy)

该程序是求解极小化问题的基本的线性搜索算法(The procedure is to solve the minimization problem based on a elementary linear search algorithm)

认知无线电网络中频谱分配技术的研究，论文和程序(CR,spectrum sharing,matlab)

基于MATLAB的原理应用，此程序可实现2d的吸收边界算法，比较简单(This MATLAB M-file implements the finite-difference time-domain solution of Maxwell s curl equations over a two-dimensional Cartesian space lattice comprised of uniform square grid cells.)

该函数用来计算时间序列的最大Lyapunov 指数 Wolf 方法 m: 嵌入维数 tau:时间延迟 data:时间序列 N:时间序列长度 P:时间序列的平均周期,选择演化相点距当前点的位置差，即若当前相点为I，则演化相点只能在|I－J|>P的相点中搜寻 lambda_1:返回最大lyapunov指数值 (This function is used to calculate the time series of the largest Lyapunov exponent Wolf method m: embedding dimension tau: time delay data: time series N: Time sequence length P: the average period of time series, the evolution of the current location of the point relative pitch poor, that is, if the current phase point is I, the evolution of the phase point only | I-J |> phase point P in search lambda_1: returns the maximum index value lyapunov)

matlab课件很有用的,对matlab学习很有帮助,希望采纳谢谢(it s very useful)
