I have the error when calling function: Check for incorrect argument data type or missing argument in call to function 'calculate​_distance_​sqr'.

In my MATLAB folder, I have class Node, and my class RRTStarSmart have some methods need the instances of the Node class as variables. My function 'calculate_distance_sqr' will calculate the distance between 2 node and I define this function as the helper function. When I call this 'calculate_distance_sqr' function, I meet the error: Check for incorrect argument data type or missing argument in call to function 'calculate_distance_sqr'. Both classes are the value classes. I think it has a trouble when I acess to the properties of class Node, but I can't see the solution. Thanks for your help!!

This is my class Node:

classdef Node
    properties
        x
        y
        parent
    end
    
    methods
        function obj = Node(n)
            obj.x = n(1);
            obj.y = n(2);
            obj.parent = [];
        end
    end
end

And this is a snippet of class RRTStarSmart that occur the error:

        function X_near = Near(obj, nodelist, node)
            n = length(nodelist) + 1;
            r = 50 * sqrt((log(n) / n));
            
            % Calculate squared distances using the helper function
            dist_table = arrayfun(@(nd) calculate_distance_sqr(node, nd), nodelist);
            
            % Find nodes in the neighborhood based on the squared distance and collision check
            X_near = nodelist(dist_table <= r^2 & ~obj.is_collision(node, nodelist));
        end
        
        % Helper function to calculate squared distance between two nodes
        function distance_sqr = calculate_distance_sqr(obj,node1, node2)
            dx = node2.x - node1.x;
            dy = node2.y - node1.y;
            distance_sqr = dx^2 + dy^2;
        end

thanks a lot !!

Can you share your full code for RRTStarSmart and runcode, so that I can see which parameters you are passing to the function and help you further.

Thanks for your attention with my problem. This is my folder with full code for RRTStarSmart and runcode.m. And this codes are inceptive and sill have some errors. My trouble occurs in 'Near' function in class RRTStarSmart.

Thank you so much

Could you show the lines of that those cause errors. Looks like there is a mismatch of passed arguments

[Duc Pham Minh]

Thanks for your attention. In my snipping figure, when I run file 'runcode' file, the code performs the RRTSS Algorithm. In methods of class RRTStarSmart, I have a function 'calculate_distance_sqr' calculating the ddisstance of 2 node (both are the instances of the Node class I show above). But I have some problem when calling this function 'calculate_distance_sqr'. The lines of that those cause errors may be in the 'Near' function or in 'calculate_distance_sqr' function in the snippet above.

for a closer checking, you can see in my zip.file in my reply to Mr.Rohit above. Thanks for your help
