matlab 带通，低通，巴特沃斯滤波器的设计(bandpass, low pass filter with butterworth type)

基于simulink建立了飞机六自由度模型，并计算其迎角。(Based on simulink established six degrees of freedom model aircraft, and calculate the angle of attack.)

用MATLAB编写的遗传算法路径规划，窗函数法设计一个数字带通FIR滤波器，一种噪声辅助数据分析方法。( Genetic algorithms using MATLAB path planning, A window function design FIR digital band-pass filter, A noise auxiliary data analysis method.)

说明：  多重分形去趋势分析,用于分析时间序列信号，如心电、脑电信号的多重分形(Multifractal detrended analysis for the analysis of time series signals, such as ECG, EEG multifractal)

这个文档是关于基于DCT数字水印算法的Matlab实现,里面详细介绍了它的原理及相应的算法(This document is about digital watermarking algorithm based on Matlab DCT implementation, which introduces the principle and its corresponding algorithm)

this is another gmm training matlab source code. it use k-means for initialization of parameter before trainig, not LBG algirhtm. so it is very helpful for GMM training

2ASK(1)通信系统仿真进行2ASK调制，其中基带信号为单极性NRZ矩形波，采用相干解调方法对带通滤波器的输出信号进行解调；(2ASK (1) 2ASK modulation for communication systems simulation, in which the baseband signal is unipolar NRZ square wave, coherent demodulation method using band-pass filter output signal demodulation )

人脸识别代码，数字图像处理 使用matlab内置函数(face detection program, using matlab function to detect human face )
