源码给出了非线性线性规划的牛顿法，代码包含函数文件，以及调用文件，下载即可运行！(Source given nonlinear Newton method for linear programming, the code contains the function file, and call the file, download to run!)

This MATLAB .m file takes a "true" image, and an "observed" image that is the true image that has been noised with uncorrelated Gaussian noise. The function then performs Tikhonov regularization to clean up the defects in the image, with the Tikhonov term used to preserve image edges as much as possible.

Range Kutta 2 method used for solving ordinary differential equation.

各种人脸识别的matlab程序，改动后可以跑得通。根据自己的需要进行选择。(Various face recognition matlab program, changes can run through. Choose according to their needs.)

辛普森公式的自适应积分：在整个积分区间使用相同的小步长 ，以保持整体精度。然而，实际应用中，函数的振荡起伏的情况处处不同，这并没有考虑到曲线的某些部分变化剧烈，需要比其他部分多加考虑的情况。而有些部分，曲线的变化缓和，因此可以采用大于平均值的步长 来进行积分。因此，引入一种能够在函数值变化大的区间采用小步长的方法是很有用的。这种方法，称为自适应积分。(Adapt integral based on Simpson integral)

Applied Numerical Analysis using matlab

说明：  解压后可以直接运行。打包里面的材料包括了1元2元三元的函数优化（都是采用二进制实现的）主要是用来实现函数的优化，具体在代码里面有详细说明。(the file is make for the beginner of learning matlab .I hope it can help you !)
