求解大型疏松方程组，ap方程组的系数矩阵，b[放回解向量

资源描述 详细介绍： 一套国外的搜索引擎，采用db数据库，不过是英文版的，经过修改我想一套正宗的SOHU系统也该诞生了！ 

本程序用于有限元方法中空间8节点单元刚度矩阵的计算，并通过文本文件实现数据间的传输，在VB中通过shell函数来调用fortran的程序，实现二者的混合编程。 -This procedure for the finite element method in space for 8-node element stiffness matrix calculation, and through text files between data transmission, in VB through shell function to call fortran procedure, the two realize mixed language programming.

独立于AVL库的存储媒体 虽现在有不少可用的AVL树库，但几乎都是工作在RAM中，当数据量小的时候，这种方式可行，但当树结构变大时时，读取和存储的时间就会大大变长，任务效率大大降低。能不能直接用磁盘进行树的操作呢？若可以，就不必进行频繁的磁盘内存交换了，本程序就实现了这个功能。实际上，这个程序无论是磁盘还是内存，都很好用。-independent of the AVL storage media is now available in a number of the AVL tree, But almost all work in the RAM, when a small amount of data, this approach feasible, but big tree structure constant, read and storage time will be much longer and the task efficiency has been greatly reduced. Can directly use the disk tree operation? If so, there is no need for frequent exchange of disk memory, the process to achieve this function. In fact, this procedure is disk or memory, are very handy.
