变分不等式求解算法之一，投影算法是将变分不等式的解进行投影，然后进行迭代。(One of the variational inequality solution algorithm, the projection method for variational inequality solution to the projection, and then iterate)

说明：  这是一种BP神经网络的的MATLAB的代码有用请下载(if it help,please go ahead)

基于MATLAB/SIMULIN，搭建的光伏系统最大功率跟踪爬山法的定步长模型(Structures of the PV system based on MATLAB/SIMULIN, climbing method of maximum power point tracking fixed step model)

智能天线算法，阵列天线波束成形，增益对准有用信号方向，抑制干扰信号(Smart antenna matlab algorithm, linear array antenna beam forming, the alignment direction of the useful signal, interference suppression direction)

这是一个经典的形变模型实施,在一个单一的文件用简单的可以理解的代码。 功能包括两部分一个简单的弱分类器和一个促进部分: 弱分类器试图找到最佳阈值的数据维数对数据进行分离成两个阶级1和1 要求的进一步提高分类器部分迭代,每一步是变化分类权重miss-classified例子。这造成了一连串的“弱分类器”,表现得像一个“强大分类器” (This a classic AdaBoost implementation, in one single file with easy understandable code. The function consist of two parts a simple weak classifier and a boosting part: The weak classifier tries to find the best threshold in one of the data dimensions to separate the data into two classes-1 and 1 The boosting part calls the classifier iteratively, after every classification step it changes the weights of miss-classified examples. This creates a cascade of "weak classifiers" which behaves like a "strong classifier" . )

非常不错的非线性非高斯环境下的粒子滤波程序(very good nonlinear non-Gaussian environment under the particle filter process)

Harris采用了一种新的角点判定方法。矩阵M的两个特征向量l1和l2与矩阵M的主曲率成正比。Harris利用l1, l2来表征变化最快和最慢的两个方向.若两个都很大就是角点,一个大一个小就是边缘,两个都小就是在变化缓慢的图像区域.(Harris adopted a new method of determining the corner. Matrix M of two feature vectors l1 and l2 with the matrix M is proportional to the principal curvatures. Harris use l1, l2 to characterize changes in the fastest and slowest in two directions. If both are great that corner, a little is a big edge, both small change is slow in the image area.)
