image_compress
本程序利用奇异值分解对3通道彩色图像进行压缩分解，具体步骤如下：
压缩过程：
1. 选取子图像大小K值，把图像分解成M×M个子图像，IMG(s),s=1,2,…, M2，其中M=N/K，原始图像IMG大小为N×N。
2. 计算这M2个子图像的平均值average，对每幅子图像减去均值图像得到新图像。
3. 计算相关矩阵R，其元素定义为 。
4. 计算R的特征值与特征向量，计算每幅子图像与最大特征向量的内积，便得到编码，即压缩后的图像。
(This procedure using singular value decomposition of 3-channel color image compression decomposition, concrete steps are as follows: compression process: 1. Select the sub-image size K value, the image is decomposed into M × M sub-image, IMG (s), s = 1, 2, ..., M2, in which M = N/K, the original image IMG size N × N. 2. M2 calculate the average of sub-image average, for each sub-image minus the new images mean images. 3. Calculation of correlation matrix R, defined as its elements. 4. Calculation of the characteristics of R value and eigenvector calculated each sub-image with the largest eigenvector of the inner product, they will have to code, that is, the compressed images.)

研一，学校开了数值分析这门课，而且要求用matlab进行上机试验，就写数值分析常微分方程的7个MATLAB算法，都是能够套用的M文件。还有我自己的上机作业。很不错的，能参考。要想要其它章的算法，我都已经上传了。(Kenichi, the school opened the numerical analysis of the course, but also carried out on machines with matlab test, on the numerical analysis of ordinary differential equations to write the seven MATLAB algorithms, are able to apply the M-file. Also on my own machine operation. Very good, can draw on. To want the algorithm to other chapters, I have already uploaded.)
