matlab 三维图广度优先搜索路径

以下是MATLAB实现三维图广度优先搜索路径的示例代码：

% 创建一个3D图形
[X,Y,Z] = meshgrid(1:10,1:10,1:10);
V = sqrt(X.^2 + Y.^2 + Z.^2);

% 定义起点和终点
start_point = [1,1,1];
end_point = [10,10,10];

% 定义移动方向
direction = [[-1,0,0];[1,0,0];[0,-1,0];[0,1,0];[0,0,-1];[0,0,1]];

% 定义队列和visited数组
queue = [start_point];
visited = zeros(10,10,10);

% 开始广度优先搜索
while ~isempty(queue)
    current_point = queue(1,:);
    queue(1,:) = [];
    visited(current_point(1),current_point(2),current_point(3)) = 1;
    for i=1:size(direction,1)
        next_point = current_point + direction(i,:);
        if next_point(1)<1 || next_point(1)>10 || next_point(2)<1 || next_point(2)>10 || next_point(3)<1 || next_point(3)>10
            continue;
        end
        if visited(next_point(1),next_point(2),next_point(3))==1
            continue;
        end
        if V(next_point(1),next_point(2),next_point(3))==0
            continue;
        end
        queue = [queue;next_point];
        visited(next_point(1),next_point(2),next_point(3)) = 1;
        if isequal(next_point,end_point)
            disp('找到终点');
            break;
        end
    end
end

% 绘制路径
path = [end_point];
current_point = end_point;
while ~isequal(current_point,start_point)
    for i=1:size(direction,1)
        next_point = current_point + direction(i,:);
        if next_point(1)<1 || next_point(1)>10 || next_point(2)<1 || next_point(2)>10 || next_point(3)<1 || next_point(3)>10
            continue;
        end
        if visited(next_point(1),next_point(2),next_point(3))==0
            continue;
        end
        if V(next_point(1),next_point(2),next_point(3))==0
            continue;
        end
        if isequal(next_point,start_point)
            path = [path;start_point];
            break;
        end
        if isequal(next_point,path(end,:))
            continue;
        end
        path = [path;next_point];
        current_point = next_point;
        break;
    end
end

% 绘制路径
hold on;
plot3(path(:,2),path(:,1),path(:,3),'r','LineWidth',2);

运行以上代码，就可以在MATLAB中实现三维图广度优先搜索路径的绘制。
