针对现行民用建筑鉴定标准适用于既有公共建筑可靠性鉴定时的内容不足、评价方法保守和评价结果信息量过少的弊端，在原可靠性鉴定规范的基础上综合国内现行规范，建立了包含抗震性能、耐久性、防火性能的既有公共建筑可靠性能评价体系。基于可拓理论将研究对象、评价指标和指标特征结合成物元，通过物元表达式建立了既有公共建筑的可拓评价模型，同时基于MATLAB编制可拓评价程序。(In view of the shortcomings that lack of appraisal contents ,conservative method of evaluation and little information of the evaluation result ,when the existing standard for appraisal of reliability of civil buildings is applied to the reliability evaluation of existing public buildings, the reliability evaluation system of existing public buildings based on existing Standard for appraisal of reliability of civil buildings including seismic performance, durability and fire resistance is established. Based on extension theory research, objects and judging indexes as well as the index characteristic values are considered as matter element. Matter-element model of existing public buildings is established in accordance with the relationship between matter-element. At the same time, the extension evaluation program is compiled based on MATLAB.)

部分实现了追踪测速迭代松弛算法，AHP层次分析法计算判断矩阵的最大特征值,小波包分析提取振动信号中的特征频率。( Partially achieved tracking speed iterative relaxation algorithm, Calculate the maximum eigenvalue judgment matrix of AHP, Wavelet packet analysis to extract vibration signal characteristic frequency.)

说明：  参加数模竞赛时搜集的关于matlab学习的资料，比较有用(Participated in several modeling contest to learn when to collect information on matlab, more useful)

说明：  利用Matlab编写程序实现以下功能：以多项式形式输入系统前向通路传递函数和反馈回路传递函数，计算系统开环增益，判定型别，根据控制系统劳斯稳定判据原理，列出得到的任意阶次系统的劳斯表，判定闭环系统稳定性，若不稳定给出具有正实部极点的数目。 （1）根据用户输入的稳定度a，计算稳定的开环增益K的范围； （2）确定系统的最大稳定度a,计算相应的开环增益K的值。 (The use of Matlab programming to achieve the following functions: polynomial in the form of input system transfer function to the path and feedback loop transfer function, system open-loop gain calculation to determine type, according to Routh stability criterion control system theory, has been listed in the system of arbitrary order Routh table to determine the stability of the closed-loop system, if the stability of a positive real part gives the number of poles. (1) According to the stability of the user to enter a, calculation of the stability of the open-loop gain of the scope of K (2) to determine the most stable system a, the calculation of the open-loop gain of the corresponding K value.)

说明：  是电力系统的电磁暂态仿真用的EMTP中的免费版ATPDraw，主要是应用于交直流的暂态仿真，这是图形界面版的(this is power system software)

简单的求逆矩阵中单个元素的程序。 用于求解逆矩阵中的单个元素值，基于定义 使用伴随阵/行列式的值求解 只适用于小矩阵。维数太大行列式的值就计算不出来了(Simple inverse matrix of individual elements in the program. For solving the inverse matrix single element values, with the value of the array/determinant of solving only apply to a small matrix-based definition. Value dimension to calculate the determinant is not too out)
