图像处理中经典的PCA算法，几乎每一步的降维之前都要用到 实用性很强(PCA classical image processing algorithms, almost every step of dimension reduction should be used in very practical before)

以天线方向图函数为例，分析了对称阵子天线、阵列天线方向图函数F(0， )随各参量变化的规律以及二维图形的特点，并讨论了直线天线阵(单向端射阵)的最大辐射方向和主瓣宽度随各参量变化的二维、三维图形特点。借助MATLAB的绘图功能，对各种天线的方向图函数的二维、三维图形进行研究，可以观察到天线辐射场在不同方向的辐射能量分布。直观清楚地表现出辐射方向图的特点。(Antenna pattern functions as an example to analyze the symmetry time around antenna array antenna pattern function F (0,) with each variation of parameters and characteristics of two-dimensional graphics, and discussed the linear antenna array (one-way end-fire array) The maximum radiation direction and the width of the main lobe of each parameter change with 2D and 3D graphics features. With MATLAB graphics functions for 2D and 3D graphics in a variety of antenna pattern function were studied, the antenna radiation field can be observed in the distribution of radiation energy in different directions. Features an intuitive clear demonstration of the radiation pattern.)

The Haar transform can be expressed in the matrix form as T = HIHT (inverse transform HTTH) where I is an NxN image matrix, H is an NxN transformation matrix and T is the resulting NxN transform. For Haar transform, the transformation matrix H contains the Haar basis functions hk(x). They are defined on a continuous, closed interval, x -[0, 1] for k = 0,1,2 ...,N -1 where N = 2n.( The Haar transform can be expressed in the matrix form as T = HIHT (inverse transform HTTH) where I is an NxN image matrix, H is an NxN transformation matrix and T is the resulting NxN transform.
