一群优化算法程序，利用这个程序可以检查fitness的变化规律(ant colony optimization (ACO))

《MATLAB程序设计教程》的源代码，非常全面哦！(" MATLAB programming tutorial" source code, very comprehensive Oh!)

利用混合同余法产生均匀随机数，并利用均匀随机数生成高斯白噪声序列。(Mixed congruential method to generate uniform random numbers, and using the uniform random number generator Gaussian white noise sequence.)

这个程序就是最基本的粒子群优化算法程序，用Matlab实现，非常简单。(This program is the most basic particle swarm optimization algorithm and Matlab, very simple.)

noisegen.m：生成白噪声并按照指定信噪比对语音进行加噪； add_noisem.m：使用输入的噪音按照指定信噪比对语音进加噪； SNR_singlech.m：输入纯净语音和加噪后的语音，计算其信噪比； my_add_noise.m：调用上述函数进行加噪操作；(noisegen.m: white noise generated by the specified signal to noise ratio of the speech plus noise add_noisem.m: use the specified input noise into the signal to noise ratio of the speech plus noise SNR_singlech.m: pure voice input and processing after the noise voice, calculate the signal to noise ratio my_add_noise.m: call the above functions plus noise operation )

说明：  ITU的MIMO无线信道模型，基于几何的模型，是对不同场景的无线信道的建模(MIMO wireless channel model)

武汉大学测绘学院平差课程设计 导线网程序 基于matlab平台(Wuhan University School of Surveying and Mapping Course Design Traverse Network Adjustment program is based on matlab platform)

说明：  通过设计模糊PID控制器，实现对直线、圆轨迹较为精准的跟踪(By designing a fuzzy PID controller, the accurate tracking of straight and circular trajectories can be achieved.)

数学形态学对信号进行去噪，效果较好，信号扰动特征得到很好保留(Morphology of the signal de-noising effect is good, the signal disturbance characteristics are well retained)
