KIVA 3V的入门介绍

说明：  9跨每跨35米桥梁响应的车桥耦合程序，使用Fortran编写(9 of 35 meters span bridge across every bridge coupled response procedures, the use of Fortran written)

说明：  lu分解矩阵求逆... =========== 紫薯紫薯...(Matrix LU decomposition inversion)

行人群体疏散仿真的社会力模型，可用于做系统仿真(Social force model for pedestrian evacuation)

开发环境没有可选项，fortran90,Fortran_90_and_Computational_Science-_codes(Computational Science codes by fortran90 )

主要用来计算抛物型偏微分方程的数值解，而且通过调用边界函数来计算方程，采用差分编程方式(Mainly used to calculate the parabolic partial differential equations numerical solution, and by calling the function to calculate the equation of the border, using differential programmatically)

使用Matlab编程，对教材74页例3.3.1进行编程仿真。其中，正电压A的值、噪声方差值、每个码元周期内的采样点数N自行设定（可设置为可调的变量）。噪声值可使用Matlab中产生高斯随机数的函数来进行仿真。贝叶斯检测判决式中，先验概率P(H1)=P(H0)，判断错误的代价因子设为1，判断正确的代价因子设为0. 按照上述参数的设定进行仿真，实现对仿真数据的贝叶斯检测判决；循环生成仿真数据，并进行判决结果的统计，即记录判决正确的次数，估计正确判决的概率。(The use of Matlab programming, teaching materials 74 pages of 3.3.1 programming simulation. Among them, the value of positive voltage A, the variance of noise, the number of sampling points in each symbol cycle (N) can be set by itself (adjustable variable). Noise values can be simulated using the function of generating Gauss random numbers in Matlab. In the Bias detection decision, the prior probability P (H1) =P (H0), the factor of error judgment is set to 1, and the correct cost factor is set to 0. According to the simulation parameters and realize the judgment of Bayesian detection simulation data; generating cycle simulation data, statistics and decision, which records the correct number of judgment, the estimated probability of correct decision.)

相场基础书籍的配套计算代码，对于学习相场法的基础同学来说极其有用(The supporting calculation code of the phase field basic book is extremely useful for the students who are studying the basic method of the phase field method.)

有限单元法基本原理和数值方法,书籍，供学习参考(The basic principle of finite element method and numerical methods)

说明：  基于矩阵QR分解的最小二乘拟合MATLAB源程序(based on QR decomposition of the matrix least squares fitting MATLAB source )

共轭梯度法求解凸二次规划，代码由C语言开发，老外编写的程序，很值得一读。(Conjugate gradient method for solving convex quadratic programming, code generated by C language development, foreigners prepared program, it is worth reading.)
