STFT parameter for ECG data

wav格式信号频谱分析，在matlab开发环境下可以很好的应用(wav format, the signal spectrum analysis, in the matlab development environment may be a good application of)

数字低通滤波器到数字带通滤波器 MATLAB编码设计(Digital low-pass filter to the digital band-pass filter design MATLAB coding)

该代码首先对ECG信号进行消噪过滤，并且对信号进行平方，加窗等处理，最后用于对QRS波形的检测，压缩文件内同时包含了2个心电数据信号，可直接用于测试(The code first ECG signal de-noising filter, and the square of the signal, such as window handle, and finally used for the detection of QRS waveform, at the same time compressed file contains two ECG data signals can be directly used to test)

说明：  使用了L形邻域进行纹理生成，是很初步的程序，用于灰度图像，而且还未考虑边界的情况，仅供参考(Use the L-shaped neighborhood texture generation, is a preliminary program for gray image, not to consider the boundary conditions for reference only)

说明：  分布估计算法的MATLAB工具箱，EDAs工具箱(Estimation of distribution algorithms in MATLAB toolbox, EDAs Toolbox)

经典的多点法形状复原算法的逐次2点法和逐次3点法的程序。本程序对当存在随机误差和系统误差时产生的评价误差进行了分析。(classic multi-point method shape recovery algorithm Successive 2:00 and 3:00 successive Act procedures. When the right procedures exist random error and systematic error, caused by the error of evaluation analysis.)

差错控制编码方向的经典书籍的matlab教程,差错编码方向的可以看看，很有用(Error control coding direction of the classic books matlab tutorial, error encoding direction can see, very useful)

matlab三维点云重建网格建立实例编程教程，对反求的很有用(Matlab 3 d point clouds reconstruction grid establish instance programming tutorial, the reverse is very useful )
