Graphshortestpath 需要 bioinformatics toolbox。
WebMar 31, 2014 · 1) Think of every pixel in the maze as node on a connected graph. 2) Define the walls as having high weights. This ensures that walls will act as separators. 3) Use a 4-connected neighborhood to link adjacent pixels/nodes. 4) Convert the maze image into a sparse Distance matrix (similar to an adjacency matrix with weights instead of ones).
