Feature-Extraction

In This Matlab Code we Use RLS Method To identify Any System Transfer Function, RLS is based of Recursive Least Squre Algorithm is very important method in System Identification.

应用于变量选择的PCA 和 PLS 程序！利用它可以选出独立的变量数!在化学中很有用！(for variable selection procedures PCA and PLS! It makes it possible to elect independent variables! In Chemistry useful!)

速度分析，用于地震勘探方面尤其有用。可以下载了自己改改，也可以用在其他方面(Velocity analysis for seismic exploration area is particularly useful. Can download their own changed, but also can be used in other areas)

将混合有白噪声的两个信号的频率提取出来，适合初学matlab的使用(Will be mixed with white noise, the frequency of two signals is extracted, the use of matlab for beginners)

Mandelbrot集和Julia集的分形图之matlab实现，特别是分形学有用。(The matlab implementation of the fractal graph of the Mandelbrot set and the Julia set of the attraction domain and the Julia set is realized, which is a great help to the fractal geometry.)

这个是EMD分解算法,相对比较简单,十分适合初学者,我开始也是从个程序入手的,觉得十分不错,与大家共享.(This is the EMD decomposition algorithm is relatively simple and very suitable for beginners, I started a program from the start, and feel very good to share with you.)

matlab 本身没有箭头功能，只有梯度，梯度不能精确，这是编写的箭头功能，可以精确定位箭头三维位置(matlab function itself has no arrows, only gradient, the gradient is not accurate, it is written in the arrow function, you can pinpoint the location of the arrow D)

计算小波相关性的几种方法，其中包括小波相关性。(Several methods of calculating the correlation of wavelet, including wavelet correlation.)

本代码是超变异模式识别的代码，能通过输入多个模式来进行识别分类。(The code is super-variant pattern recognition code, through the importation of a number of models to identify the classification.)
