Graphshortestpath 需要 bioinformatics toolbox。
WebApr 29, 2014 · I've recently become interested in graph theory and after investing with the bioinformatics toolbox for MATLAB I have found the graphshortestpath function incredibly useful. However, when using the function the run times are always very similar, whether I set the function to Breadth-first search, Dijkstra's algorithm or Bellman Ford … WebThe function finds that the shortest path from node 1 to node 6 is path = [1 5 4 6] and pred = [0 6 5 5 1 4]. Now you can determine the shortest paths from node 1 to any other node within the graph by indexing into pred. For example, to figure out the shortest path from node 1 to node 2, you can query pred with the destination node as the first ...

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.
