This paper describes a parallel algorithm for the LU decomposition of band matrices using Gaussian elimination. The matrix dimension is n 脳 n with 2 r1 diagonals. In the case when 1 r 2 p an optimal number of the processors, p, is determined according to the equation p = [(r +1)/2...
高斯消元法 高斯消元法(Gaussian elimination)是求解线性方阵组的一种算法,它也可用来求矩阵的秩,以及求可逆方阵的逆矩阵。它通过逐步消除未知数来将原始线性系统转化为另一个更简单的等价的系统。它的实质是通过初等行变化(Elementary row operations),将线性... Tony Ma 0 20152 三对角矩阵(Tridiagonal Matrices...
step② takes O(n3) for Gaussian Elimination Thus, O(n3) totally. More precisely, we have n linear constraints and 2e+k variables, which are the coefficients of these two polynomial. 编辑于 2020-06-07 18:50 编码理论 信息与编码理论 赞同3添加评论 分享喜欢收藏申请...
BACKWARD GAUSSIAN ELIMINATIONPARALLEL ALGORITHMWe present a parallel algorithm for the solution of tridiagonal linear systems based on the method of partitioning and backward elimination. A given N N system is partitioned into r blocks each of size n n (N = rn n even). Within each block the ...

Then, Gaussian elimination algorithm (Higham, 2011) can be used to restore the original set of packets P. Two important parameters determine the level of computational complexity involved in this scheme: (1) Galois field size, and (2) generation size n (the number of packets combined to ...

In numerical linear algebra, the tridiagonal matrix algorithm, also known as the Thomas algorithm (named after Llewellyn Thomas), is a simplified form of Gaussian elimination that can be used to solve tridiagonal systems of equations. - armancodv/tdma
by using Gaussian elimination, which requires13M3multiplications and divisions. When the number of states is large, exact solution ofEq. (34)can be computationally prohibitive. An alternative is to use successive approximations to obtain an approximate solution. This is the basis of the modified pol...
