说明：  用matlab实现窄带信号的测向算法，可实现的(using Matlab achieve narrowband signal to the test algorithm, achievable)

光伏MPPT 电池模型 以及最大功率追踪~~~~~~~~~(PV MPPT battery model and the maximum power tracking ~~~~~~~~~)

实上，我们可以把系统框图中外编码器、交织器和内编码器三部分级联后的总体，看作一个级联码的编码器，同理，外译码器、去交织器和内译码器三部分级联后的总体构成了级联码的译码器。 本次仿真外编码采用（7，4）HAMMING码，内编码采用（2，1，3）卷积码。交织编码采用（7，4）卷积交织编码或循环等差交织编码。除特别说明外，交织编码采用前者即（7，4）卷积交织编码。 (failed to translate)

对确定的一个负反馈系统，进行稳定性判断、最小相位系统判断；求取零点、极点、放大系数；绘制阶跃响应图。(To determine a negative feedback system, judge, judge the stability of minimum phase system calculating the zeros, poles, amplifying coefficient drawing step response diagram.)

回归的各种分析实例以及matlab代码，包括各种数学应用，比如线性回归，非线性回归，逐步回归(Examples of regression analysis, as well as a variety of matlab code, including a variety of mathematical applications such as linear regression, nonlinear regression, stepwise regression)

Most countries are facing a multiplicity of challenges directly related to the pr ent ways in which they currently generate and use energy. Human-induced climate change, rising pollution levels, decreasing energy security, and resource wars are all increasingly linked to the widespread use of non-renewable sources of energy. These interrelated challenges present an ongoing and pressing policy-making dilemma to develop and implement sound energy solutions. Evidence regarding the imperative need for creative energy solutions is amassing a variety of reputable sources. The Fourth Assessment Report by the Intergovernmental Panel on Climate Chance (IPCC) ranks amongst the most salient of these sources. This IPCC report clearly points out that drastic reductions in the use of fossil fuel use are essential to reduce greenhouse gas (GHG) emissions to thereby minimize the most detrimental impacts of climate change.
