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.)

MATLAB编写利用牛拉迭代法求解简单电力系统潮流。程序可以分别运用真实值和标幺值计算，可以区分有无变压器计算。程序开始时需要输入节点数量、互联节点之间线路的阻抗等初始化参数，运行可得潮流结果，详见程序内注释。(Written in MATLAB to solve simple oxen pulling power flow using an iterative method. The program can use the true value, respectively, and the per-unit value calculation, you can distinguish whether the transformer calculations. When the program begins to enter initialization parameters such as impedance between the number of nodes, interconnected nodes lines running trend results can be obtained, the detailed program notes.)
