Loop through array containing coordinates points
显示 更早的评论
Hi, im trying to loop through an array containing coordinates in order to plot them and automatize this process, I've tried doing the following:
p0 = [1, 1];
p1 = [2, 3];
p2 = [4, 3];
p3 = [3, 1];
cords = [p0, p1, p2, p3];
for index = 1:length(cords)
pX = cords(index) % don't know how to take first value (1) not working
pY = cords(index) % same here
disp(pX)
disp(pY)
plot(pX,pY,.....)
end
I can't get something like this to work, I always end up getting just the first point instead of both of them.
I've also tried setting the points like
p0 = [1 1] %with spaces
But I don't know how to make it work. If you could help me I'd be very grateful, thanks

Try this...
p0 = [1, 1];
p1 = [2, 3];
p2 = [4, 3];
p3 = [3, 1];
cords = [p0, p1, p2, p3];
N=length(cords);
for i = 1:length(cords)
pX{i} = cords(i); % don't know how to take first value (1) not working
pY{i} = cords(i); % same here
end
pX_value=[pX{:}];
pY_value=[pY{:}];
disp(pX_value)
disp(pY_value)
plot(length(pX_value),pX_value,'*')
ylim([0 5])
