采用ECG信号进行HRV的时域分析、频域分析的Matlab代码(Matlab code for HRV time domain analysis and frequency domain analysis using ECG signal.)

Lyapunov Exponents Toolbox (LET) provides a graphical user interface (GUI) for users to determine the full sets of Lyapunove exponents and dimension of their specified chaotic systems. This version of LET can only run on MATLAB 5 or higher versions of MATLAB. It has been tested under Windows and Unix. LET may also run on other platforms. The original version of LET has only 200 lines while the GUI version of LET has almost 2000 lines. The GUI makes the program become more sophisticated and run slower but allows the users to observe the calculated results immediately, so that they can decide whether the results are convergent or not.(Lyapunov Exponents Toolbox (LET) provides a graphical user interface (GUI) for users to determine the full sets of Lyapunove exponents and dimension of their specified chaotic systems.
