视频检索，图像识别等方面的内容，用于matlab(Video retrieval, image recognition and other aspects)

perturb and observe tracking algorithm

给出两个chirp信号相加后，由瞬时频率定义求出的瞬时频率曲线，说明瞬时频率的不确切性；(The sum of two chirp signals are given, after the definition of instantaneous frequency derived from the instantaneous frequency curve, indicating lack of precision in the instantaneous frequency )

Implements the traditional benchmark formulation used in optimization literature

克里金空间插值算法在matlab上的功能函数(kriging interpolation)

说明：   画chen系统混沌及分岔图,里边包含几个文件，没有说明，谢谢关注(display the picture of chaos of chen. about several files. i am sorry for no discrimination. thank you for pudn!)

幂法是一种计算矩阵主特征值(矩阵按模最大的特征值)及对应特征向量的迭代方法, 特别是用于大型稀疏矩阵。 (The power method is a method of calculating the matrix eigenvalue (matrix largest characteristic value) and the iterative method of the corresponding feature vector, particularly for large sparse matrix.)

指纹识别源码---matlab版--附图指纹图像(Fingerprint identification source code--- matlab version- attached fingerprint image)

说明：  Copula理论及应用实例，调用ecdf函数和ecdfhist函数绘制沪、深两市日收益率的频率直方图(Copula theory and application examples, calls ecdf function and ecdfhist function draws frequency Shanghai and Shenzhen histogram of daily returns)

此代码主要是用simulink搭建的一个三电平SVPWM模型，能出图，实用型的一个代码。(This code is to use a three-level SVPWM simulink model structures, to a map, a practical code.)
