中文说明：无向图和有向图的关联矩阵和邻接矩阵的相互转换，其中F表示所给出的图的相应矩阵，W表示程序运行结束后的结果。既有已知矩阵转化为相应的矩阵。 当f=0时,为邻接矩阵转换为关联矩阵；当f=1时,关联矩阵转换为邻接矩阵。在命令窗口输入矩阵F和命令W=incandadf(F,f)。
English Description：
The transformation between the incidence matrix and adjacency matrix of undirected graph and digraph, where f represents the corresponding matrix of the given graph and W represents the result after the program runs. The known matrix is transformed into the corresponding matrix.
