Why is the attribute 'DiagonalSearch' in plannerAStarGrid unusable? What is the code for the extension method of sub nodes in plannerAStarGrid? I want to modify the extension

%Plan Obstacle-Free Path in Grid Map Using A-Star Path Planner
%Plan the shortest collision-free path through an obstacle grid map using the A* path planning algorithm.
%Generate a binaryOccupancyMap object with randomly scattered obstacles using the mapClutter function.
rng('default');
map = mapClutter;
%Use the map to create a plannerAStarGrid object.
planner = plannerAStarGrid(map,"DiagonalSearch",'on');
%Define the start and goal points.
start = [2 3];
goal = [248 248];
%Plan a path from the start point to the goal point.
plan(planner,start,goal);
%Visualize the path and the explored nodes using the show object function.
show(planner)

Could you explain what you mean about it being "unusable" ? I do not see any obvious error when the code is run? What should we be looking for?

'DiagonalSearch' is an unrecognized parameter. For a list of valid name value pair parameters, refer to this function

The document for.

'DiagonalSearch' seems to be unusable. I want to know how to extend child nodes?

Which MATLAB version are you using?
