摘要
提出了一种利用闭合区域确定矩阵中重复符号代表的最小行列数,从而得到矩阵最小行列数的方法。包含3个部分:矩阵元素归一化;寻找闭合区域,建立重复符号间的制约关系;通过重复符号间的关系得到重复符号代表的最小行列数,确定矩阵结构。实验表明,该方法能够正确快速地给出复杂矩阵的行列数,确定矩阵结构。
A method is proposed to analyze the structure of matrices including repeated symbols.The method uses the borders of closed regions to obtain the minimum row-column numbers of matrix by the minimum row-column numbers that every repeated symbol occupies.This method is composed of three parts: make the matrix elements normalized;search the restrictive relationship between the repeated symbols;determine the structure of matrix by the minimum row-column numbers represented by the repeated symbols.The experiments show the method can obtain the row-column numbers of complex matrix efficiently and determine the structure of matrices.
