说明：  在simulink中搭建Buck-Boost开环电路，但这种开环电路不好调整输出电压，于是又搭建了一种简单闭环电路(Buck-Boost open-loop circuit is built in simulink, but this open-loop circuit can not adjust the output voltage, so a simple closed-loop circuit is built.)

非常好用的MATLAB程序，不下会后悔的(MATLAB is very useful procedure, we will regret over the)

function [ndata,a]=splinenormalize(data) The function SPLINENORMALIZE normalizes with splines, the data(n,m) where n specifies the number of time points, and m is the number of IMF components. The normalization is carried out with both maxima and minima hence emax is taken as the absolute sign.

K-SVD可以看做K-means的一种泛化形式，K-means算法总每个信号量只能用一个原子来近似表示，而K-SVD中每个信号是用多个原子的线性组合来表示的。 K-SVD通过构建字典来对数据进行稀疏表示，经常用于图像压缩、编码、分类等应用。(K-SVD can be regarded as a generalized form of K-means. The total K-means algorithm can only approximate one signal for each semaphore, and each signal in K-SVD is a linear combination of multiple atoms To express. K-SVD through the construction of the dictionary to sparse data representation, often used for image compression, encoding, classification and other applications.)
