This thesis consists of two parts. The first one was that boundary value problem was discrete with five point difference method. Three kinds of memory formats were studied, which were full matrix, half band width and row compress sparse. Full matrix memory format and half band width memory format first was contrasted. The results show that half band width has efficiency in space. Then the algebraic system of finite element method was solved by Gauss-Seidel iteration method to popular row compress sparse memory format.
本论文由两部分组成,第1部分针对边值问题,用5点差分格式进行离散,并对离散矩阵这类大型稀疏矩阵,研究了系数矩阵的3种存储格式的优劣,即:满矩阵存储格式、半带宽存储格式和按行压缩稀疏存储格式,首先我们将满矩阵存储方式和半带宽存储格式进行了对比,迭代法的数值实验表明:利用半带宽存储的矩阵在空间运算方面具有高效性;然后针对目前数值实验中流行的按行压缩稀疏存储格式,实现了有限元离散代数系统的迭代法的求解。
