摘要
本文提出一种紧凑改进节点方程的算法,与目前流行的改进节点法(MNA)相比较,不仅可减少方程阶数,而且可避免出现零主元和主对角线奇异矩阵块。
In this paper,an algorithm of Compact Modified Nodal Equation is developed. As Compared with the current MNA,our algorithm requirs less variables and gives no zero diagonal elements and diagonal singular metrix in the coefficient metrix.
