摘要
利用代数方法,给出无向图为连通图的充分必要条件,进一步得到判别"0—1"正线对称矩阵可幺化的简便方法。
By using an algebraic method, a necessary and sufficient condition of the connected graph with the non-digraph is given. Further, a simple distinguish method is obtained for distinguishing the ＂0-1 ＂ symmetric matrix of the positive line as a one-matrix.
