AffineTransformation computes and applies the geometric affine transformation to a 2-D image. The program main functions are: - Load Image: Load the image to be transformed. - Transform Image: Computes the transformation matrix from the transfo

Input: XY(n,2) is the array of coordinates of n points x(i)=XY(i,1), y(i)=XY(i,2) Output: Par = [a b R] is the fitting circle: center (a,b) and radius R Note: this fit does not use built-in matrix functions (except "mean"), so it can be

绘制二维密度散点图，根据x，y的最大最小值将坐标分成若干小格，然后统计落在每个小格里的点数，最后形成的就是一个矩阵，然后直接出图-Drawing two-dimensional density scatter plot, according to the x, y minimum and maximum values ​ ​ of the coordinates into a number of small cells, then every little statistic

二．二维小波分解与重构程序说明 1.主函数 mymain.m:通过调用所写的函数对信号进行二维小波分解与重构 main.m:利用MATLAB中小波变换函数实现 2.调用的子函数 function [x2,cA,cV,cH,cD] mydwt2(x,Lo_D,Hi_D) 函数mydwt() 对 x 进行二维小波分解 输入参数为x,Lo_D,Hi_D x为输入信号，Lo_D为低通滤波器,Hi_D为高通滤波器 输出参数：cA,cV,cH,cD —— 是
