Description: 这是用于线性方程组求解的ILUK预处理算法的实现。在VC++编译通过。矩阵采用压缩稀疏行格式存储（CSR），采用如下结构存储：struct Distmatrix {double **ma int **ja,dimension,*nnzrow } 很容易移植到自己定义数值计算软件包中。经本人测试计算效率比Fortran写的高很多（比如与Sparskit2比较）。-This is used for solving linear equations ILUK preconditioning algorithm. In VC++ Compiled through. Matrix using compressed sparse row storage format (CSR), using the following structure of memory: struct Distmatrix (double** ma int** ja, dimension,* nnzrow) be easily transplanted to their own definition of numerical computation package. I tested by calculating the efficiency ratio is much higher Fortran write (for example, compared with Sparskit2).

Description: 这是Yousef Saad编写的矩阵运算的Fortran软件包（A basic tool-kit for sparse matrix computations (Version 2),包含常见的排序，预处理(ILU分解等)，Krylov子空间迭代法，以及有限差分等方法得到的算例等。有不少很实用的子程序（比如稀疏矩阵相加、相乘等等，可以学习专家的设计哟！）。极力向学习大型线性方程组数值解的人推荐（不足之处就是Fortran实现，本人觉得还是C语言好）。-Yousef Saad This is prepared in the Fortran matrix calculation package (A basic tool-kit for sparse matrix computations (Version 2), contains the common sort, preconditioning (ILU decomposition, etc.), Krylov subspace iteration method, as well as limited differential and other methods such as numerical example. there are many very practical subprogram (such as sparse matrix add, multiply, etc., can learn from experts in the design yo!). hard to study large-scale numerical solution of linear equations of the people Recommended (Fortran is inadequate to achieve, I feel good or C language).
