[Algorithm] SPARSKIT2.tar DL : 0: 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).

[Algorithm] superlu_3.1.tar DL : 0: SuperLU is a general purpose library for the direct solution of large, sparse, nonsymmetric systems of linear equations on high performance machines. The library is written in C and is callable from either C or Fortran. The library routines will perform an LU decomposition with partial pivoting and triangular system solves through forward and back substitution. The LU factorization routines can handle non-square matrices but the triangular solves are performed only for square matrices. The matrix columns may be preordered (before factorization) either through library or user supplied routines. This preordering for sparsity is completely separate from the factorization. Working precision iterative refinement subroutines are provided for improved backward stability. Routines are also provided to equilibrate the system, estimate the condition number, calculate the relative backward error, and estimate error bounds for the refined solutions. -SuperLU is a general purpose library for the direct solution of large, sparse, nonsymmetric systems of linear equations on high performance machines.

[Algorithm] sparsematrix DL : 0: 求解大型对称或非对称方程组，采用稀疏矩阵存储及求解算法，在电力系统仿真分析软件中得到应用-Sparse1.3 is a flexible package of subroutines written in C used to quickly and accurately solve large sparse systems of linear equations. The package is able to handle arbitrary real and complex square matrix equa- tions. Besides being able to solve linear systems, it is also able to quickly solve transposed systems, find determinants, and estimate errors due to ill-conditioning in the system of equations and instability in the computations. Sparse also provides a test program that is able read matrix equations from a file, solve them, and print useful information about the equation and its solution. Sparse1.3 is generally as fast or faster than other popular sparse matrix packages when solving many matrices of similar structure. Sparse does not require or assume symmetry and is able to perform numerical pivot- ing to avoid unnecessary error in the solution. It handles its own memory allocation, which allows the user to forgo the hass

[Algorithm] 稀疏矩阵转置 DL : 0: ·在矩阵中，若数值为0的元素数目远远多于非0元素的数目，并且非0元素分布没有规律时，则称该矩阵为稀疏矩阵，并用三元组表表示。该算法只扫描两遍原三元组表，就能够获得稀疏矩阵的转置矩阵(In matrix, if the number of elements 0 is far more than the number of non 0 elements, and the distribution of non 0 elements is not regular, it is called sparse matrix, and it is expressed by three tuple table. The algorithm only scanned the original three tuple table two times, and can obtain the transposed matrix of the sparse matrix.)
