lowpass FIR filter 的MATLAB代码(MATLAB code of lowpass FIR filter )

采用c++调用matlab写的一个sift算法，其中调用matlab只是使用其中几个函数。可以很准确的检测出sift特征点。(Using c++ to call a matlab write sift algorithm, which used to call only a few matlab function. Can accurately detect the feature points sift.)

说明：  关于Julia集和Mandelbrot集的MATLAB程序(the programs of Julia set and Mandelbrot set with MATLAB)

inverse-dual tree complex wavelet transform (i-dtcwt) matlab codes

实现QAM调制解调，分为16QAM、64QAM，包括瑞利信道的仿真程序，可以供初学参考。(Implementation of QAM modulation and demodulation, divided into 16QAM, 64QAM, including Rayleigh channel simulation program, can be reference for beginners.)

MATLAB平台运行的禁忌搜索算法代码，亲测可用(Tabu search algorithm code running on MATLAB platform, pro test available)

基于Mtalab实现的指纹特征提取的实例(Mtalab realize fingerprint-based feature extraction examples)

说明：  一个非常受欢迎的贝叶斯网络matlab工具箱(A very popular Bayesian network toolbox matlab)

绘制庞加莱截面图的程序。先通过solveLor.m来求出一系列点，然后代入Poincare_section 程序绘制庞加莱截面。 通过观察Poincare截面上截点的情况可以判断 是否发生混沌：当Poincare截面上有且只有一个不动点或少数离散点时，运动是周期的；当Poincare截面上是一封闭曲线时，运动是准周期的 当Poincare截面上是一些成片的具有分形结构的密集点时，运动便是混沌。 (Poincare section drawing program. First obtained by solveLor.m to a series of points, and then drawn into the program Poincare Poincare section. By observing the situation on the Poincare section cut points can determine whether chaos occurs: When there is only one fixed point or a few discrete points on the Poincare section, the motion is periodic When is a closed curve on the Poincare section, the motion is quasi- When is the point of having a dense fractal structure on some stretches of the Poincare section, the motion is chaotic period.)

说明：  直接将ECG信号转换为HRV信号，具体阈值可以通过人工调节，识别率很高，采用自适应差分阈值法和小波变化结合(The ECG signal is directly converted into HRV signal, the specific threshold can be adjusted manually, and the recognition rate is very high. The adaptive difference threshold method and wavelet change are combined.)
