前推回推法计算配电网潮流，已经通过验证，结果正确。同时计算出电压、电流、网损。(Calculation of forward and backward push distribution networks, has been validated, the results correctly. At the same time to calculate voltage, current, power loss.)

首先是对matlab程序设计的概述，其次是matlab程序结构的详细讲解以及M文件的简介(An instroduction about the program deisgn of matlab )

Ⅰ层模型声波波场数值的有限差分模拟程序,利用有限差分方法,对声波在地下的传播进行模拟(Ⅰ layer model acoustic wave finite difference numerical simulation program using finite difference method, the spread of sound waves in the ground to simulate)

这是学习matlab语言的一个非常好的电子教案，对初学者特别有用。(This is the matlab language learning a very good electronic lesson plans, particularly useful for beginners.)

HEED protocol used in wireless sensor networks

在DAB系统中的频率同步，载频同步，参考一下Carrier frequency offset estimation of DAB receiver based on phase reference symbol(In the DAB system frequency synchronization, carrier frequency synchronization, refer to Carrier frequency offset estimation of DAB receiver based on phase reference symbol)

fit_ML_normal - Maximum Likelihood fit of the normal distribution of i.i.d. samples!. Given the samples of a normal distribution, the PDF parameter is found fits data to the probability of the form: p(r) = sqrt(1/2/pi/sig^2)*exp(-((r-u)^2)/(2*sig^2)) with parameters: u,sig^2 format: result = fit_ML_normal( x,hAx ) input: x - vector, samples with normal distribution to be parameterized hAx - handle of an axis, on which the fitted distribution is plotted if h is given empty, a figure is created. output: result - structure with the fields sig^2,u - fitted parameters CRB_sig2,CRB_u - Cram?r-Rao Bound for the estimator value RMS - RMS error of the estimation type - ML

由于地球的上空有76颗依星，所以依星可以定位到地球的任意一个地方，该程序主要完成地理位置的定位(Because there are 76 above the Earth s Iridium, Iridium so you can navigate to any place of the Earth, which is mainly geographic location)
