一个希尔伯特变化的程序代码，不晓得对不，不敢用，请指教？(Hilbert change a code, I do not know do not, dare not, please advice?)

说明：  这是基于周期图改进的welch的功率谱估计，这种方法是在经典周期图的基础上改进而来的，效果很不错(This is based on the improved welch periodogram power spectral estimation, this method is based on the classical periodogram improvement came, the effect is very good)

说明：  雨流计数方法源代码，可以用于各种工程类的分析之用(rainflow counting method)

说明：  主要介绍了在Matlab中怎样仿真FIR滤波器组的设计(Describes how the simulation in Matlab, the design of FIR filter banks)

通过ucdos获得一段波长区间的模场分布，而后用matlab获得光子晶体光纤的非线性(Through the cudos get a wavelength of interval mode field distribution, then use matlab, the nonlinear photonic crystal fiber )

基于MATLAB编写的集对分析与K均值聚类相结合的环境风险评价方法，熵权法作为指标权重确定方法。(MATLAB based on set prepared for analysis of environmental risk assessment and K-means clustering method of combining, entropy law as a method of determining the index weight.)

说明：  模拟电动汽车（私家车，公交车，出租车）充电，进行充电负荷预测(Prediction of Charging Load by Simulating Electric Vehicle Charging)
