AVL树实现高效查找，平衡二叉树，随结点加入而旋转，始终保证树的平衡性，资料中是该树的所有文件（包含debug）-Efficient search AVL tree, balanced binary rotation as nodes join and always ensure that the balance of the tree, the tree of all files (including debug information)

用Matlab编程，实现解决该问题的单样本训练BP网络，设置一个停止迭代的误差Emin和最大迭代次数。在调试过程中，通过不断调整隐层节点数，学习率η，找到收敛速度快且误差小的一组参数。产生均匀分布在区间[-4，4]的测试样本，输入建立的模型得到输出，与Hermit多项式的期望输出进行比较计算总误差（运行5次，取平均值）-Using Matlab programming, to solve the problem of single sample training BP network, set
