旅行商问题的IAGA算法。好象很不错的程序。matlab编写的(IAGA Algorithm for Traveling Salesman Problem. It seems very good procedure. matlab prepared)

面对大学繁琐的物理化学实验数据，本文提供了用matlab处理的常用方法(The face of the University of complicated physical and chemical experimental data, this paper provides a common method of dealing with matlab)

1、使用牛顿法求sqrt（2）； 2、用牛顿法求 fx=(x-1)*(exp(x-1)-1)的误差以及误差比； 3、用牛顿法及其他两种方法求 fx=x^4-4*x+x^2的重根 (1, using Newton' s method for the sqrt (2) 2, using Newton' s method for the fx = (x-1)* (exp (x-1)-1) error and error ratio 3, using Newton' s method and the other two method, to calculate fx = x ^ 4-4* x+ x ^ 2 re-root)

matlab example shows you can work that easily.

％ 用途：选列主元Gauss消去法解线性方程组ax=b ％ 格式：x=nagauss2(a,b,flag) a为系数矩阵，b为右端列向量，flag若为0，则显示中间过程 ％ 否则不显示，默认值为0，x为解向量 ( Usage: Selected Principal Gauss elimination method solution of linear equations ax = b format: x = nagauss2 (a, b, flag) a for the coefficient matrix, b for the right side column vector, flag if it is 0, it shows the middle Otherwise, the process does not appear, the default value is 0, x for the solution vectors)

the code for boundary extraction

考虑微分方程在如下步长分布采用向前Eular、向后Eular，梯形公式、改进Eular和四阶龙格库塔方法计算近似值(procedure of approximate error using matlab)

基于Rssi的三边测量的定位算法，可以直接生成demo进行计算，十分方便(Rssi trilateral localization algorithm based measurements can be calculated directly generate demo, very convenient)

A self-organizing map (SOM) or self-organizing feature map (SOFM) is a type of artificial neural network (ANN) that is trained using unsupervised learning to produce a low-dimensional (typically two-dimensional)

Reed-So lomon (RS)码是目前最有效、应用最广的差错控制编码之一,是一类具有很强纠错能力的多进制BCH 码,它既可以纠正突发误, 也可以纠正随机错误。视、磁记录系统等方面。本文用matlab详细仿真实现RS编译码(Reed-So lomon (RS) code is the most effective, the most widely used one of error-controlling codes, is a kind of strong ability of the error correction into BCH code, it can correct mistakes sudden, also can correct random errors. RS code is mainly used in real-time higher mobile communications system, the deep space communications, digital satellite television, magnetic recording system, etc. In this paper, using matlab detailed simulation (RS decoder)
