这是一篇关于用MATLAB实现动态规划顺序算法的一个论文性质的文章(This is an article on using MATLAB in order to achieve dynamic programming algorithm is the nature of a paper article)

基于matlab实现sift描述符程序，经测试可用，效果有待提高！(achieve sift descriptor， program has been tested and is available, the effect needs to be improved!)

此为基于MATLAB平台计算指纹图像中两点之间穿越纹线数(For fingerprint processing is calculated through the ridge)

GMDH的MATLAB源代码，是主程序，也就是gmdhbuild.文件。与之配套的测试文件gmdhtest.m、输出误差gmdhpredice.m会接着发出。(GMDH The MATLAB source code, is the main program, which is gmdhbuild. File. Accompanying test file gmdhtest.m, output error will be followed by a gmdhpredice.m.)

说明：  该程序代码用于求解超越方程，绘制频散曲线，自行可以更改基本参数或方程形式加以利用(Solve the transcendental equation, draw the dispersion curve)

Induction machine equation

In this file we implemented a dwt watermarking method in matlab

说明：  共轭梯度法（Conjugate Gradient）是介于最速下降法与牛顿法之间的一个方法，它仅需利用一阶导数信息，但克服了最速下降法收敛慢的缺点，又避免了牛顿法需要存储和计算Hesse矩阵并求逆的缺点，共轭梯度法不仅是解决大型线性方程组最有用的方法之一，也是解大型非线性最优化最有效的算法之一。 在各种优化算法中，共轭梯度法是非常重要的一种。其优点是所需存储量小，具有步收敛性，稳定性高，而且不需要任何外来参数。(The Conjugate Gradient method is a method between the steepest descent method and the Newton method. It only needs to use the first derivative information, but overcomes the shortcomings of the steepest descent method and avoids the need for the Newton method to store And the calculation of Hesse matrix and the inverse of the shortcomings, conjugate gradient method is not only to solve large-scale linear equations one of the most useful methods, but also solution for large-scale nonlinear optimization of one of the most effective algorithm. In a variety of optimization algorithms, conjugate gradient method is a very important one. The advantage is that the required storage capacity is small, with step convergence, high stability, and does not require any external parameters.)
