WebGraph Theory Functions. Graph theory functions in the Bioinformatics Toolbox™ apply basic graph theory algorithms to sparse matrices. A sparse matrix represents a graph, any nonzero entries in the matrix represent the edges of the graph, and the values of these entries represent the associated weight (cost, distance, length, or capacity) of the edge. Web说明. d = distances (G) 返回矩阵 d ,其中 d (i,j) 是节点 i 和节点 j 之间的最短路径的长度。. 如果图进行了加权(即 G.Edges 包含变量 Weight ),则这些权重用作沿图中各边的距离。. 否则,所有边距离都视为 1 。. d = distances (G,s) 将源节点限制为由 s 定义的节点,这样 ... highlands weather https://mbrcsi.com
