上百种Matlab程序设计的源码，希望对初学者有一些帮助。(Hundreds of Matlab programming source code, and they hope to have some help for beginners.)

说明：  1、随机生成一个5*5矩阵A，元素符合均匀分布；再随机生成一个5*5矩阵B，元素符合正态分布。对A和B进行加、减、乘、除、比较等矩阵运算，查看运算结果。 2、创建5阶魔术矩阵，求A的行列式、特征值、逆、秩、迹、条件数。 3、假设矩阵 ，求A的LU分解、正交分解、特征值分解、奇异值分解。 4、创建6阶单位稀疏矩阵，并显示其全部元素。 (1, randomly generated a 5* 5 matrix A, elements in line with uniform distribution then randomly generated a 5* 5 matrix B, elements in line with normal distribution. Pairs of A and B to add, subtract, multiply, divide, comparison matrix operations, view the results of operations. 2, create a 5-order magic matrix, find A, determinant, eigenvalues, inverse, rank, trace, the condition number. 3, assuming that matrix, find A, LU decomposition, orthogonal decomposition, eigenvalue decomposition, singular value decomposition. 4, create a six-order unit of sparse matrix, and display all of its elements.)

运用shancen格子玻尔兹曼模型模拟两相分离，验证可行(Use shancen lattice Boltzmann model to simulate two-phase separation, verification feasible)

说明：  广义预测控制的matlab程序源码，直接运行仿真，M文件(GPC)

说明：  关于圆盘耦合摆的研究，将介绍单圆盘耦合发电机模型和双圆盘耦合发电机模型的非线性方程组。通过对方程组的分析和MATLAB模拟计算，指出前者电流有稳定的周期解，后者在两圆盘角速度不同时可能进入混沌态，并且通过数值计算其Lyapunov指数（其中一个，出现了正值）来证明其混沌态(Research on the disk coupled pendulums, will introduce the model of a single disc and double disc coupling generator generator model coupled nonlinear equations. Equations through the analysis and MATLAB simulation, that the former current of a stable periodic solution, which is not the same in the two-disc angular velocity may enter the chaotic state, and by numerical calculation of its Lyapunov index (one of which, there have been positive) to prove the chaotic state)
