In this paper, symbolic code matrix ,constant matrix and count matrix are defined .The first twomatrices are used to describe the elemental expression of augmented matrix and the nede admittance equa-tion is thus obtained. The third matrix is used to obtain the incoming degree matrix, and according to thematrix all the 1- factors of the Coates graph are given. By using the data code, the determinant is expandedand the same items in the expansion are merged. Thus the symbolic network function in which no term can-cellation occurs is generated. 相似文献

本文引入符号码数组、常数数组和记数数组,前二数组用来描述增广矩阵的元素表达式,建立节点导纳方程,后一数组用来写出入度矩阵,然后根据入度矩阵产生Coates流图的全部1-因子增益。在展开行列式时利用符号代码合并同类项,消去相消项,从而得到无相消项的全符号网络函数。 相似文献
