撕裂法与矩阵结构

Tearing and Structure of Matrix

适当地划分子网络,可使电路方程组的系数矩阵具有对称阶梯形结构。方程组就能用逐个地消去非零块的方法求解。由此得出撕裂法的使用条件与算法。

With the subnetworks reasonably divided, the coefficient matrix equations may be of the structure of symmetrical stairs so that equations can be solved through dliminating one by one the nozero blocks, thus, the conditions of appication and algorithms for tearing are worked out.
