compress a picture, using kmeans Clustering

人工智能matlab仿真！！个人杰作，包含 粒子群算法，遗传算法，蚁群算法等等，非常有趣，希望能帮到您学习matlab(Artificial Intelligence matlab simulation! ! Individual masterpieces, including the particle swarm optimization, genetic algorithm, ant colony algorithm, etc., is very interesting, I hope to help you learn matlab)

利用SVM做回归线性测试。对于大盘指数的有效预测可以从整体上观测股市的变化提供强有力的信息，所以对上证指数的预测很有意义。通过对上证指数从1990.12.20-2009.08.19每日的开盘数进行回归分析，最终拟合的结果是：均方误差MSE=2.35705 e-005，平方相关系数 R=99.9195 。SVM的拟合结果还是比较理想的。(Make use of SVM linear regression testing. For the market index can predict the observed changes in the stock market as a whole to provide a strong information, so it makes sense to predict the Shanghai index. Through the Shanghai Composite Index opened daily from 1990.12.20-2009.08.19 number of regression analysis, the results of the final fit are: mean square error MSE = 2.35705 e-005, the square of the correlation coefficient R = 99.9195 . SVM fitting result is quite satisfactory.)

说明：  RRT 的思想是快速扩张一群像树一样的路径以探索（填充）空间的大部分区域，伺机找到可行的路径。(The idea of RRT is to rapidly expand a group of tree-like paths to explore (fill) most areas of space, waiting for the opportunity to find feasible paths.)

用ＭＡＴＬＡＢ实现不同线型、不同颜色，不同位置画出多个矩形(Using MATLAB to achieve different line, different colors, different locations to draw multiple rectangles)

采用AHP方法，采用比较矩阵，对各层目标参数进行权重分配(AHP method using the target parameters weight distribution)
