由黄等提出了对EMD的改进方法EEMD，5条程序经过尝试均可使用(By Wong et proposed an improved method for EMD EEMD, 5 bar program has been tried and can be used)

这是一艘补给船的仿真程序，里面有全面的船舶数据和具体的仿真曲线(a supply ship simulation)

说明：  这是关于AM调制的matlab程序，对初学调制的人很有帮助，有仿真图片(AM modulation matlab program, beginner modulation helpful, simulation picture)

matlab 实现PCA算法，可以输出识别率，有详细注释，值得一用(Face Recognition Using PCA algorithm procedure, with annotations, 88 recognition rate )

由matlab解决多旅行商问题，并且包括矩阵计算等功能(From matlab to solve multi-traveling salesman problem, and includes features such as matrix calculation)

基本的拉格朗日乘子法(又称为拉格朗日乘数法)，就是求函数f(x1,x2,...)在g(x1,x2,...)=0的约束条件下的极值的方法。其主要思想是引入一个新的参数λ（即拉格朗日乘子），将约束条件函数与原函数联系到一起，使能配成与变量数量相等的等式方程，从而求出得到原函数极值的各个变量的解。 (Basic Lagrange multipliers (also known as Lagrange multiplier method), is of a function f (x1, x2 ,...) in g (x1, x2 ,...)= 0 constraints under the conditions of extreme value methods. The main idea is to introduce a new parameter λ (the Lagrange multiplier), the constraint function is linked together with the original function, so variables can be paired with an equal number of equations equation, thus obtained by the original function extreme solution of the various variables.)

说明：  基于MATLAB的源码程序，用来实现读取PPM格式的图像(MATLAB-based source program to read PPM format image)
