基于SFAM神经网络集成的土地评价.pdf.对matlab算法进行很详细的应用(SFAM neural network-based integrated land evaluation. Pdf. On matlab algorithm in great detail the application of)

说明：  一个用MATLAB编写的数字水印算法实例，加入了高斯噪声(One with a digital watermarking algorithm written in MATLAB examples, adding Gaussian noise)

1．用Matlab产生正弦波,矩形波,以及白噪声信号，并显示各自时域波形图 2．进行FFT变换，显示各自频谱图，其中采样率，频率、数据长度自选 3．做出上述三种信号的均方根图谱,功率图谱,以及对数均方根图谱 4．用IFFT傅立叶反变换恢复信号，并显示恢复的正弦信号时域波形图(1. Produce sine wave, square wave, and the white noise signal with Matlab, and their time-domain waveform display 2. FFT transform, display each spectrum, where the sampling rate, frequency, length optional data 3. RMS to make maps of the three signals, power spectrum, as well as the number of RMS map 4. Restored by inverse Fourier transform IFFT signal and displays the time domain waveforms sinusoidal signal recovery)

用simulic编写了生成信号 很详细很好用呢(singal simulic)

语音信号的iir滤波器设计,从带有噪音的信号中提取原始声音.目前，MP3播放器一般功率放大器的工作频率范围就是这个范围。但是大部分有用的和可理解的信息的频率在200到3500Hz之间。所以我们可以在这个范围间滤波，达到使声音可理解的要求。现将数字滤波器的设计指标设为通带截止频率fb=600HZ,阻带频率fc=1200HZ,通带波纹Ap=1dB，阻带波纹As=40dB,要求确定H(z)。(design of the iir filter, get the original voice without noise)

pid and fuzzy control for inverted pendulum

C++0x library for parsing options/command line argument

This set of files enables working more easily with functions of functions for concise and powerful code. A few highlights of this way of working: * Map multiple inputs to multiple functions and assign multiple outputs with a single line. * Use conditionals (like "if"), loops, and recursion in anonymous functions.

matlab实现的短时过零率，mfcc和lpc源代码语音段都有(matlab to achieve short-term zero crossing rate, mfcc and lpc voice segment has source code)
