Mathematics concepts for electrical engineers

可以实现多智能体编队，即多个分散智能体聚集到一块且相互之间保持一定的距离向前运动(Can achieve multi-agent formations that gathered more than a dispersion agent, and maintain a certain distance from each other moving forward)

一个使用数学方法生成波形声音文件的源代码，可以载入预置数学公式，保存8位和16位单声道声音文件，可以设置振幅、频率、持续、采样等参数，可以调整波形斜面，回声。 这个代码值得推荐！(The use of mathematical methods to generate a waveform sound files of source code, can load preset mathematical formula, save 8 and 16-bit mono sound files, you can set the amplitude, frequency, continuous, sampling and other parameters, you can adjust waveform slope, echo . It is recommended this code!)
