题目:稀疏矩阵是指那些多数元素为0的矩阵.利用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.实现一个能进行稀疏矩阵基本运算的运算器.基本要求:以带行逻辑连接信息的3元组顺序表表示稀疏矩阵,实现两个矩阵相加,相减和相乘的运算.矩阵的输入形式采用3元组表示,而运算结果的矩阵则以通常的阵列形式列出.概要设计:1.以带行逻辑连接信息的3元组顺序表表示稀疏矩阵2.本程序包含2个模块:(1) 各集合定义模块(2) 主程序模块-topics : sparse matrix refers to those elements for most of the matrix 0. Using sparse features storage and computation can be greatly reduced storage space and improve computational efficiency. One can achieve for sparse matrix operations basic computing device. Basic requirements : OK logical connection with the three yuan Information Group the order said the sparse matrix table to achieve two matrices together, subtract and multiply arithmetic. Matrix entry forms using three yuan Group said, and the results of the matrix operations while the usual array listed. summary of design : 1. in line with the logic of information linking the three element group said sparse chronology matrix 2. this program contains two modules : (1) Set module (2) main program module
