用matlab设计的常用数学公式和计算公式的程序，写在一个WORD文档里(Matlab design with mathematical formula and the formula commonly used procedures, written in a WORD document where)

1、Rayleigh_Doppler_singlePath.m 产生单径Rayleigh衰落，采用了6种方法并进行了比较，推荐使用第6种方法； 2、Rayleigh_Doppler_multiPath.m 根据多条径的延时和强度，产生频率选择性衰落； 在单径和多径两个程序中，均提供了其功率谱的输出代码； (1, Rayleigh_Doppler_singlePath.m Single Path Rayleigh fading generated using the six kinds of methods and compared recommend using the first six kinds of methods 2, Rayleigh_Doppler_multiPath.m Drive under a number of delay and intensity, resulting in frequency selective fading in single-track and multi-path two procedures, which provide the power spectrum of the output code )

利用内点法计算电力系统潮流计算，matlab源代码(The use of interior point method to calculate the power flow calculation, matlab source code)

说明：  模拟n束光束的干涉图像。可以是任意多束。偏振方向可以自己选取(Simulation of n-beam-beam interference image. Multi-beam can be arbitrary. Able to select the polarization direction)

一个关于卫星导航方面的ekf滤波程序，请大家互相共享一下(a satellite navigation on the ekf filtering process, please share what each other)

simple way to implement pca for beginner

说明：  应用小波理论进行模态分析，求出固有频率和阻尼比(modal analysis use the wavelet method)

本程序主要用于DDS算法的验证,可以生成正弦波，占空比可调的方波，三角波；其中频率控制字可调，生成波形的频率也可调。(This procedure is mainly used for verification DDS algorithm, can generate sine wave with adjustable duty cycle square wave, triangle wave including adjustable frequency control word to generate adjustable frequency waveform.)

说明：  BP神经网络 基于美国西储大学轴承故障数据(BP neural network based on bearing failure data of Western Reserve University)
