Graphshortestpath 需要 bioinformatics toolbox。

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.
