CAN SOMEONE HELP ME WITH THE PLOT?

I am new to MATLAB and could use some help with the issue I am facing, here is the code.

nodes = [(1:10); (10:10:100); (10:10:100)]';

segments = [(1:17); floor(1:0.5:9); ceil(2:0.5:10)]';

figure; plot(nodes(:,2), nodes(:,3),'k.');

hold on;

for s = 1:17

if (s <= 10) text(nodes(s,2),nodes(s,3),[' ' num2str(s)]); end

plot(nodes(segments(s,2:3)',2),nodes(segments(s,2:3)',3),'ko');

end

[d, p] = dijkstra(nodes, segments, 1, 10)

i = 1

for n = 2:length(p)

plot(nodes(p(n-1:n),2),nodes(p(n-1:n),3),'r-.','linewidth',2);

grid on

anim(i) = getframe;

i = i+1;

pause(2)

end

Result-

p =

1 2 4 6 8 10

Instead of intersecting points 3,5,7,9 can I make them follow a different path avoiding those points?

Please Help.

Can you make a drawing of the result you expect?

Here is the path marked in bold, sorry I could not draw all the nodes hope you will understand.

Thanks a lot for helping out.

My solution

x = 1 : 12;
y = x;
ind = [1 2 4 6 7 8 11];
plot(x,y,'.r')
hold on
for i = 1:length(ind)-1
    x1 = x(ind(i));
    x2 = x(ind(i+1));
    y1 = y(ind(i));
    y2 = y(ind(i+1));
    if ind(i)+1 == ind(i+1)
        plot([x1 x2],[y1 y2])
    else
        plot([x1 x1 x2],[y1 y2 y2])
    end
end
hold off
