传感器节点故障诊断，分布式WMFD故障诊断算法，基于相邻节点信息比较的诊断方法(Distributed sensor network fault detection based on weighted median )

阈值法实现灰度图像分割，效果不错，可行，可以借鉴(Threshold method to achieve gray-scale image segmentation, the effect of a good, viable, can learn from)

股票指数模拟为几何布朗运动，GBM。 参数有五个： s0，dt（time step），均值，标准差，到期时间T； 利用子函数进行10万条轨道的monte carlo 模拟到期日（3个月）的指数点数，从而估计在买入信号出现后，3个月后的损益情况，主要用来估算VAR (Financial risk analysis on Matlab monte carlo simulation, stock index simulation for geometric Brownian motion, GBM. )

用Matlab软件搭出来的光伏电池模型，通过输入光照、温度、电压参数，可以实现光伏电池的一般特性。(Take out using Matlab software model of photovoltaic cells, by entering the light, temperature, voltage parameters, you can achieve the general characteristics of photovoltaic cells.)

谱聚类的matlab实现，其中包括k-means的实现，谱聚类聚类结果要优于k-means的聚类结果(Spectral clustering matlab code, including the code of k-means, spectral clustering results is better than k-means clustering results)

a radix-2,3 and 5 FFT, hopefully this is new and helpful :)

本源代码主要实现谐波小波的分解及重构的matlab程序。(Source code of the main harmonic wavelet decomposition and reconstruction of the matlab program.)

说明：  利用反函数方法,在均匀分布的基础上产出具有瑞利分布的概率分布的数据.(By inverse function method, based on the output of uniform distribution with the Rayleigh distribution the probability distribution of the data.)

计算方法中，拉格朗日插值法的源代码。在最后，绘出了拉格朗日插值法的图像和原图像的比较。原创。(Calculation method, Lagrange interpolation source code. In the end, draw a comparison image and the original image Lagrange interpolation. Original.)

This is a matlab code for Amplitude shift keying and Phase shift keying
