Description: 稀疏矩阵是指那些多数元素为零的矩阵。本文利用稀疏矩阵“稀疏”特点进行存储和计算可以大大节省存储空间,提高计算效率。通过采用标准C++语言设计实现了矩阵的乘法运算器。稀疏矩阵的乘法运算可用于解决许多实际的应用问题.提出一种新颖的稀疏矩阵相乘算法,算法实现中将计算单元由单个元素扩展至行向量,避免了矩阵的转置,减少了扫描次数。利用十字链表表示稀疏矩阵,再将建立好的两个相同行列数的稀疏矩阵进行相乘运算。

Description: 用三元组表实现稀疏矩阵的转置运算
一个阶数较大的矩阵中的非零元素个数S相对于矩阵元素的总个数t很小时,即非
零元素个数s占矩阵元素的总个数t的25%~30%时,称该矩阵为稀疏矩阵称.
由于稀疏矩阵中非零元素的分布没有任何规律,在存储非零元素时,必须保存该非
零元素所对应的行下标和列下标.这样,存储的每个稀疏矩阵中的非零元素都需要(行
下标,列下标,元素值)三个参量来唯一确定,将这种存储结构称为稀疏矩阵的三元组
表示法.
稀疏矩阵中的所有非零元素构成三元组线性表.若把稀疏矩阵的三元组线性表按顺
序存储结构存储,则称为稀疏矩阵的三元组顺序表.
-group table with three yuan achieve sparse matrix transpose operation of a larger order of the matrix number of non-zero elements relative S matrix elements in the total number t very hour, that is the number of non-zero elements s matrix elements for the total number of t 25% ~ 30%, matrix said the sparse matrix said. because of sparse matrix distribution of non-zero elements of no laws, storage nonzero elements, we must preserve the non-zero elements corresponding to the line indexed and listed indices. so, each storage sparse matrix of non-zero elements are required (under the demarcation line are indexed, elements of value) three parameters to determine only, This storage structure will be known as the sparse matrix method ternary group said.

Description: 稀疏矩阵
设矩阵A mn 中有s个非零元素,若s远远小于矩阵元素的总数(即s<<m×n),则称A为稀疏矩阵。
1、稀疏矩阵的压缩存储
为了节省存储单元,可只存储非零元素。由于非零元素的分布一般是没有规律的,因此在存储非零元素的同时,还必须存储非零
元素所在的行号、列号,才能迅速确定一个非零元素是矩阵中的哪一个元素。稀疏矩阵的压缩存储会失去随机存取功能。
其中每一个非零元素所在的行号、列号和值组成一个三元组(i,j,a ij ),并由此三元组惟一确定。
稀疏矩阵进行压缩存储通常有两类方法:顺序存储和链式存储。链式存储方法【参见参考书目】。
2、三元组表
将表示稀疏矩阵的非零元素的三元组按行优先(或列优先)的顺序排列(跳过零元素),并依次存放在向量中,这种稀疏矩阵的顺序
存储结构称为三元组表。 -sparse matrix based matrix A are mn s nonzero elements, if s is far less than the total number of matrix elements (s
