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.

Program for designing local area network

1、 降噪步骤： （1） 一维信号的小波分解。选择一个小波并确定分解的层次，然后进行分解运算。 （2） 小波分解高频系数的阈值量化。对各个分解尺度下得高频系数选择阈值进行软阈值量化处理。 （3） 一维小波重构。根据小波分解的最底层低频系数和各高频系数进行一维小波重构。 matlab里面有关于去噪的函数，你可以找一下~~ 这说的只是基本原理，希望有所帮助(1, noise reduction steps: (1) one-dimensional signal wavelet decomposition. Select a wavelet decomposition level and determining, and then divide the operation. (2) high coefficient wavelet thresholding. For each decomposition scales have high coefficient selection threshold soft threshold quantization. (3) one-dimensional wavelet reconstruction. According to the lowest level of the low frequency wavelet coefficients and high frequency coefficients of each one-dimensional wavelet reconstruction. There are about denoising matlab function, you can find some ~ ~ This says just the basic principle, we hope to help)
