Passino所提出的细菌优化算法matlab源程序(Passino proposed optimization algorithm matlab source of bacteria)

PID控制器，比较简单，可以作为matlab的GUI界面的教学使用。(PID controller.It is relatively simple, and can be used as the teaching tool of the Matlab GUI interface.)

画出射线跟踪的图形,自动填充的技术，自己写的，希望能有用(Draw the pattern of the ray tracing)

希尔伯特变换理论及其在工程领域的应用，介绍了原理及其实现方法(hibert transform)

实现功能 1) 在用户界面设置录音时长并实时录音 2) 调节放音幅度、播放原声并进行时域、频域绘图 3) 对收集的声音进行倒放处理并播放 4) 对收集声音进行回声处理并播放，比对时域波形 5) 对收集声音进行回响处理并播放，比对时域波形 6) 对经过回声处理的声音进行回音消除并比对时域波形 7) 采用自适应滤波器消除采集声音中的环境噪音 8) 设计相应的滤波器组成均衡器对收集的声音进行处理并播放 9) 男女声识别 10) 设计参数可调的滤波器对采集的声音进行处理 (1) in the user interface to set the recording length and real-time recording 2) to adjust sound, played acoustic amplitude and time domain, frequency domain mapping 3) to upend the collection of sound and play 4) to collect sound echo processing and playback, than in the time domain waveform 5) to collect sound echoes, processing and playback, than in the time domain waveform 6) to echo and treated with echo s voice than in the time domain waveform 7) using adaptive filter to eliminate ambient noise in acquisition voice 8) to design the corresponding filter to process the voice of equalizer to collect and display 9) NanNvSheng recognition 10) tunable filter design parameters for voice processing )

本源码是在matlab环境中进行连续小波变换，不用调用matlab中的小波函数。(The source code is in the matlab environment, continuous wavelet transform, do not call matlab in the wavelet function.)

matlab的一些有用的程序，需要的可以看看(Some useful matlab program, the need to look at)

信息隐藏算法lsb的matlab实现，可以实现正确的隐藏及提取(Lsb of information hiding algorithm matlab implementation, can achieve the proper extraction of hidden and)
