coordinates.xlsx

Hi all, I want to draw path between points, but the paths cannor be diagonal. Therefore the paths should have corners. Think it as a rectangle, you want to move from a corner to another corner, but cannot move diagonally. How can I show that on matlab? The coordinates are attached.

Thanks

Can you show your attempts? What have you tried?

clear all
clc
p = xlsread('coordinates');
for k =1:length(p)
for i = 1:length(p)
    
    x = [p(k,1) p(i+1,1) p(i+1,1) p(i+1,1)];
    y = [p(k,2) p(1,2) p(1,2) p(i+1,2)];
    
    x1 = [p(k,1) p(k,1) p(k,1) p(i+1,1)];
    y1 = [p(k,2) p(i+1,2) p(i+1,2) p(i+1,2)];
    plot(x,y,x1,y1)
    
    i = i+1;
   hold on
end
k=k+1;
end

when k is larger than 1, the code does not print the thing I want.

I reached a succes

p = xlsread('coordinates');
x = p(:,1);
y = p(:,2);
plot(x,y,'.r')
hold on
for i = 1:length(x)-1
    plot([x(i) x(i+1)],[y(i) y(i)])
    plot([x(i+1) x(i+1)],[y(i) y(i+1)])
    pause(0.5)
end
hold off

In the end I should have a 50x50 matrix which stores the lengths of each path

clc
clearvars
close all
XY = xlsread('coordinates');
result1=pdist2(XY,XY,'cityblock')

This is how I store my lengths, as I said earlier, if any path crosses any obstacle then the length of that path should be inf or something very large(the value actually does not matter)

While visiting the points in the file 'coordinate' if I the line crosses an obstacle(which is attached as file)

It's too complicated for this forum. You should incorporate your own script

To connect each point with each points use this code:

for i = 1:length(x)-1
    for j = i+1:length(x)-1
        plot([x(i) x(j)],[y(i) y(i)])
        plot([x(j) x(j)],[y(i) y(j)])
        pause(0.01)
    end
end
