声波传输损耗，有利于节约你的时间，希望广大爱好程序计算者喜欢 (acoustic transmission loss)

这是一个瑞丽信道的仿真程序，我试过，能运行，大家多多参考。(This is a Ruili channel simulation program, I tried to run, everyone can reference.)

fcm kfcm segmentation

这是一个有关于模式识别中的isodata算法的matlab源码。 大家可以看看。有详细注释(on the isodata pattern recognition algorithm Matlab source. We can look at. Detailed Notes)

主要讲解了matlab的基本语法，ppt版本。(Mainly on the basic syntax matlab, ppt version.)

自己写的最基本的pso测试函数是x^2+y^2，内置6个函数可供选择(original pso)

实现三维定位，利用chan算法与taylor算法想结合的方法，减小了定位误差(Three-dimensional positioning, would like to combine the use of the chan algorithms and taylor algorithm method to reduce the positioning error)

改进aic准则ARIMA模型，通过调整误差来寻找p和q(ARIMA model)

This is a case where a array is introduced

说明：  svpwm仿真模型，可以在matlab中的simulink中打开，介绍描述清晰，适合初学者了解(SVPWM simulation model, can be opened in MATLAB Simulink, the introduction description is clear, suitable for beginners to understand)
