  • auxiliary matrix

例句与用法

  • Instead , there needs to store only the original coefficient matrix , some auxiliary matrices for the preconditioner and several vectors in the iteration methods . further , the core of the iteration is the matrix - vector multiplication and the solution of the auxiliary equations corresponding to the preconditioner . if the solution of the auxiliaries spend not very much , the computational cost in each iteration step will be very cheap , due to the fact that the sparsity of the matrix can be exploited sufficiently
    与直接法相比,迭代法只需存储原系数矩阵、对应于预处理的几个辅助矩阵与少量几个向量,且迭代中除求解辅助线性方程组外,其余的计算主要是稀疏矩阵与向量乘积,从而能充分利用稀疏性减少计算量,但迭代法的收敛速度一般与系数矩阵的谱分布有关。
