[Other] 矩阵相加的算法 DL : 0: 当稀疏矩阵A和B均以三元组表作为存储结构时，试写出矩阵相加的算法，其结果存放在三元组表C中。解：这个算法有点繁，要考虑到两个稀疏矩阵的非零元素不是一一对应的，在建立新的三元组表C时，为了使三元组元素仍按行优先排列，所以每次插入的三元组不一定是A的，按照矩阵元素的行列去找A中的三元组，若有，则加入C，同时，这个元素如果在B中也有，则加上B的这个元素值，否则这个值就不变如果A中没有，则找B，有则插入C，无则查找下一个矩阵元素。 -sparse matrix A and B were 3 groups, as a storage structure and try to write together the matrix algorithm, results stored in ternary Group C table. Solution : This is a bit complicated algorithm, taking into account the two nonzero sparse matrix element is not one-to-one. the establishment of a new ternary Group C table, in order to enable groups of elements remaining three yuan prioritize OK, So inserted three yuan each group is not necessarily A, in accordance with the matrix elements ranks to find a group of three yuan, and if so, C is added, and if this element is B, plus the B value of the element, Otherwise, the value on the same if not A, then B to find, then insert C, no one will find under the matrix elements.

[Other] LDL-2.0.1.tar DL : 0: 对基于稀疏矩阵存储技术的对称正定稀疏矩阵进行LDL分解，C++编写-LDL is a set of concise routines for factorizing symmetric positive-definite sparse matrices, with some applicability to symmetric indefinite matrices. Its primary purpose is to illustrate much of the basic theory of sparse matrix algorithms in as concise a code as possible, including an elegant new method of sparse symmetric factorization that computes the factorization row-by-row but stores it column-by-column. The entire symbolic and numeric factorization consists of a total of only 49 lines of code. The package is written in C, and includes a MATLAB interface.
