Ising模型铁磁—顺磁相变现象的Monte Carlo模拟的matlab程序(Ising model of ferromagnetic- paramagnetic phase transition phenomenon of the Monte Carlo simulation program matlab)

这个程序就是最基本的粒子群优化算法程序，用Matlab实现，非常简单。只有几十行代码。(Algorithm for this process is the most basic particle swarm optimization procedures, using Matlab implementation is very simple. Only a few dozen lines of code.)

[X,Y,Z]=cylinder2(x,y,z,r,N,o) 向量X，Y，Z轴定义圆柱面中心线 和矢量r定义圆柱面半径，并已 为的x，y，z的长度相同 N是周围围点的数量。默认值 为N= 100。 Ø 定义了矩阵圆柱generatix（圆圈）椭圆 表面。其内容以0和1之间的值，并适用于 小学和中学的母线轴。值的defeault Ø =的（长（x），2）。 矩阵X，Y，Z轴确定圆柱面，冲浪（的X，Y，Z）的显示器 圆柱面。( [X,Y,Z]=cylinder2(x,y,z,r,N,o) Vectors x, y, z define the central line of cylindrical surface and vector r defines the radius of cylindrical surface, and has the same length as x, y, z. N is the number of points around the circumference. The default value is N = 100. Matrix o defines ovality of the generatix (circle) of cylindrical surface. Its elements take values between 0 and 1 and apply to the primary and secondary axis of generatrix. The defeault values are o=ones(length(x),2). Matrices X, Y, Z define the cylindrical surface, surf(X,Y,Z) displays the cylindrical surface. )

格子boltzmann 方法，D2Q9模型，圆柱绕流，采用反弹-漫反射综合边界条件(Lattice boltzmann method, D2Q9 model flow around a cylinder, using the bounce- Diffuse integrated boundary conditions)

基于matlab的，关于lax-wendroff,lax-friedrichs,一阶迎风格式，一阶warming-beam格式的计算流入门简单算例(simple examples of lax-wendroff, lax-friedrichs, first-order upwind, first-order warming-beam based on MATLAB.)

THE MATLAB COMMUNICATION TOOLBOX

可以用这份代码做粒子滤波，效果还行，这个是无迹的算法(This code can be used for particle filtering.)

基于MATLAB的(二维、三维)相机标定（说明书+图片+源程序）(MATLAB-based (two-dimensional, three-dimensional) camera calibration (description+ image+ source code))
