经济学的数值方法 非线性优化。涉及Broyden s Method Powell s Hybrid Method,定价问题(Broyden s Method Powell s Hybrid Method，pricing set)

该代码是基于HOG的图像分类检测，用于图像分类(The code is based on HOG image classification and detection, used for image classification.)

说明：  鲸鱼优化算法(WOA)也是一种元启发式优化算法。一种新的模拟座头鲸狩猎行为的元启发式优化算法(鲸鱼优化算法，WOA)。目前的工作与其他群优化算法相比的主要区别在于，采用随机或最佳搜索代理来模拟捕猎行为，并使用螺旋来模拟座头鲸的泡泡网攻击机制。(Whale optimization algorithm (WOA) is also a meta heuristic optimization algorithm. A new meta heuristic optimization algorithm (whale optimization algorithm, WOA) is proposed to simulate the hunting behavior of humpback whales. The main difference between the current work and other swarm optimization algorithms is that the random or optimal search agent is used to simulate the hunting behavior, and the spiral is used to simulate the bubble net attack mechanism of humpback whales)

常用的数据标准化方法及Matlab程序实现,在多属性综合评价问题中，为了消除量纲差异带来指标不可公度性问题，往往需要对原始评价矩阵进行标准化处理，通过将不同量纲进行变换，变为无量纲的标准化指标。 下面，对六种比较常见的标准化处理方法进行介绍并给出Matlab程序实现。

matlab的回归算法例程， 包括回归算法(regression algorithm matlab routines, including the handover algorithm)

This file has the codes which calculate tha characteristics of yagi-yuda antenna.

Find intersection of two curve! enjoy it

The function translates from labels of a binary tree to corresponding rows (R) and columns (C) of a 2 dimensional matrix storing the tree according to predefined convention, given below. The storing matrix preserves the fractal-like topology of the tree.

这是偏微分方程在图像处理中的应用一书的配套光盘，非常好的东东哦(This is a partial differential equations in image processing applications supporting CD-ROM book, very good stuff oh)
