[Data structs] sparselib_1_6 DL : 0: 　SparseLib + +是一个c++类库,为在不同的计算机平台进行有效稀疏矩阵的计算。这个软件组成对象包含了目前正在使用的几种稀疏矩阵存储格式(在这个版本:压缩行、压缩列和协调格式),提供基本的功能,节约稀疏矩阵存储空间和计算时间。-SparseLib++ is a C++ class library for efficient sparse matrix computations across various computational platforms. The software package consists of matrix objects representing several sparse storage formats currently in use (in this release: compressed row, compressed column and coordinate formats), providing basic functionality for managing sparse matrices, together with efficient kernel mathematical operations (e.g. sparse matrix-vector multiply). Routines based on the Sparse BLAS are used to enhance portability and performance. Included in the package are various preconditioners commonly used in iterative solvers for linear systems of equations. The focus is on computational support for iterative methods, but the sparse matrix objects presented here can be used on their own.

[Data structs] tudebianli DL : 0: 根据《数据结构》学所内容，使用C++中的封装、继承、运算符重载、类模板等技术，完成以上各个数据结构类的设计。-According to the data structure of the study content, use the inheritance, sealing, in c++ operator overloaded, class template technology, complete the above all data structure kind design. subtraction, the zero members all change the, again call operation addition. Multiplication, in can under the condition of multiples respectively, the each line processing: a column such as: if M in the first line of the first and last a nonzero, the first and the last, and N respectively in the first line and the last line of non-zero member multiplication. The results obtained by the position of the corresponding kept in, to deal with to the downside. The results in the same position on adding together. Finally with sparse matrix
