摘    要:提出了计算广义逆AT,S^(2)的一个并行算法,并且证明了理论结果:广义逆AT,S^(2)的并行计算复杂性,一般约束线性方程组Ax=b,x∈T,b∈R(A)求解,和计算m+n-h阶矩阵A的特征多项式和行列式有同样的增长率,其中h=rank(G),R(G)=T和N(G)=S.

关 键 词:并行算法  并行计算复杂性  广义逆AT,S(2)

Abstract:We propose a parallel algorithm for computing the generalized inverse AT,S(2) and prove a theoretical result:the parallel arithmetic complexities for computing the generalized inverse AT,S(2), the general restricted linear equation Ax = b, x ∈ T, b ∈ R(A) , and the characteristic polynomial and the determinant of the matrixA of order m + n-hhave same growth rate, whereh= rank(G), R(G) = TandN(G) = S.
Keywords:parallel algorithm  parallel arithmetic complexity  generalized inverse AT,S(2)
