用Matlab编写 的基于RSSI的信号 强度传输过程中通过损耗进行无线传感器网络WSN节点定位。(WSN ,RSSI)

//给定整数n，产生所有[2n]上的匹配（matching） //将其视为一个所有块大小均为2的集合分拆 //以a_i表示其第i个元素所在的集合号 //输出格式为 a1 a2 a3 ... //满足 //a_{i+1} <= max { a1,a2,...a_i } + 1 (//a given integer n, have all [2n] on the matching (matching)// will be considered as an all pieces are two sets of a split// a_i said in its i elements of a collection of lies// output format for a1 a2 a3 ...// meet// a_ i (a))

本程序可用于线性插值,Fortran源码用于插值计算。(Program for linear interpolation.)

说明：  abaqus周期性边界条件代码，可以参考学习(ABAQUS periodic boundary condition code can refer to learning)

非线性有限元及程序这本书,很有用的，程序也很全面(NONLINEAR FINITE ELEMENT AND PROGRAM)

数值分析中运用matlab用hermit插值多项式逼近函数(Numerical analysis using matlab function hermit interpolation polynomial approximation)

用Roe格式求解黎曼激波管问题的Fortran源代码。可以通过MUSCL插值来提高求解精度。适合计算流体力学的初学者参考学习。(Riemann shock tube problem with Roe scheme. You cam improve the accuracy by MUSCL interpolation. This code is suitable for CFD beginners.)

说明：  基于mises屈服准则的随动强化模型的umat子程序(Follow up reinforcement UMAT)

说明：  自动控制原理课程设计，建立倒立摆的非线性数学模型用SIMULINK图形库实现。(The course design of the principle of automatic control and the establishment of the nonlinear mathematical model of the inverted pendulum are realized by the Simulink graphic library.)

截断奇异值分解技术是一种正则化方法，用于不适定问题的数值计算(Truncated Singular Value Decomposition is a regularizaiton method for ill-conditioned problem computation.)
