求二维点对问题，但是没有实现不知道怎么做？(the distans of some points )

说明：  求解各复杂混沌程序的最大李指数，以便于分析混沌系统的各种性质.(Chaotic procedures for solving the complex the largest Lyapunov exponent in order to facilitate analysis of various properties of chaotic systems.)

所谓跳频，比较确切的意思是：用一定码序列进行选择的多频率频移键控。(The so-called frequency hopping, the exact meaning is: a certain code sequence selected frequency to frequency shift keying.)

说明：   matlab函数，可实现golay编码和译码，包括（23，11）和（24，12，8） (matlab function, can be realized golay encoding and decoding, including the (23,11) and (24,12,8))

本组设计的声音导引系统使用双MCU结构，采用基于时间差的声源定位算法（利用三路接收器的时差信号）结合PID算法判断并控制移动声源的速度。本设计的特色在于使用四阶Butterworth带通滤波器对声音信号进行处理，使其具有较强抗干扰能力。且系统设计性价比高，功耗低。(Our group design the Sound Guidance System based on Bi-MCU configuration, using time difference sound source orientation arithmetic（the time difference signal from three receivers）combining PID arithmetic to determine and control the mobile sound source’s velocity. The feature of the designation is processing the sound signal by four-order Butterworth band-pass filter. This enhances the anti-jamming ability. Furthermore, the system has the high performance and low price.)
