清空环境变量 网络结构建立 遗传算法参数初始化 迭代求解最佳初始阀值和权值 遗传算法结果分析 把最优初始阀值权值赋予网络预测 BP网络训练 BP网络预测 清空环境变量(Empty the environment variable Established network structure Genetic algorithm parameter initialization Iterative Solution optimum initial thresholds and weights Analysis of Genetic Algorithms The optimal initial threshold value is assigned to the right network prediction BP network training BP network prediction Empty the environment variable)

牛顿迭代算法，可以解决非线性优化问题，但是求出的是局部最优解，应用时应该注意(Newton iterative algorithm to solve nonlinear optimization problems, but find the local optimal solution, the application should be noted)

THIS CODEIS USEFUL FOR COMPRESSION OF DATA USING BITMASK AND RLE

一个简单的在figure中用鼠标画直线的例子。最终是想在matlab环境下编一个用鼠标画贝塞尔曲线的程序，现在正在研究中。(A simple figure using the mouse in a straight line drawn examples. Ultimately would like to matlab environment made a Bezier curve with the mouse painting process, now being investigated.)

a classification base on Baysian classifier , I did pca, lda, normalization on features either
