MATLAB的SNR计算

useful data for matlab

按照粒子群算法以及最近邻法则对全体样品进行分类(In accordance with Particle Swarm Optimization method to classify the samples of the whole)

一个关于机器人轨迹规划的小程序，感觉不错，自己写的，希望对大家有帮助(IT IS about robot,in matlab,maybe it is useful to you ,hope you will like it)

Matlab 官方工具箱使用说明 buildgui图形用户界面设计手册.pdf(Official Matlab toolbox for use graphical user interface buildgui Design Manual. Pdf)

emd经验模式分解算法，特别适用于非线性非平稳信号的分析处理(Empirical Mode Decomposition)

对多径信道的仿真 输入码元,是一行矩阵,可以是实数也可以是复数 ％fs是输入码元的比特率 ％fd是多普勒频移 ％n_delay是多径信道的径数 ％t_delay是多径信道各径的时延时间 ％p_delay是多径信道各径的功率db值 (Of the multipath channel simulation input symbol is a line matrix, can be a real number can also be plural fs is the input symbol of the bit rate fd is the Doppler frequency shift is n_delay multipath channel diameter of a few t_delay is multipath channel time delay of the Path p_delay is multi-path channel the power of the diameter db value)

图像分割的方法有许多种，其中阈值分割的方法很常用，提供一种基于otsu算法的图像分割方法，很实用。(There are many kinds of method of image segmentation, threshold segmentation method is commonly used, provide a method of image segmentation based on otsu algorithm is very practical)

粒子群算法解决背包问题。包含matlab 源程序，和一份报告。我的一份作业(Particle swarm algorithm to solve knapsack problem. Matlab source code included, and a report. I have a job)

说明：  matlab的时间序列分析工具，可以计算最大lyapunov指数、相关维数等，还可以进行相空间重构(matlab time series analysis tools, you can calculate the maximum lyapunov index, correlation dimension, phase space reconstruction can also)
