rectangle intersect with line and display which line or point got intersect?

Dwy0 = 200;
Dwy = 100;

B1x = data(:,2);
B2x = data(:,2)+4*7.*D;
B3x = data(:,2)+4*7.*D;
B4x = data(:,2);
B1y = data(:,3) + (D/2);
B2y = data(:,3) + (Dwy/2);
B3y = data(:,3) - (Dwy/2);
B4y = data(:,3) - (D/2);

xv = [B3x,B4x,B1x,B2x];
yv = [B3y,B4y,B1y,B2y];

x2v = [B4x B1x];
y2v = [B4y B1y];

AA=intersect([xv,yv],[x2v,y2v])
plot(AA,'b.')
hold on;grid on
plot(xv,yv,'.')
% plot(x2v,y2v)

Do you have a question?

[Prakash Choudhary]

In this code how can i show that the line x2v,y2v intersected by the rectangle and its for n rectangle with n lines the realtion between that i cant be able to display in here or simulate this thing!!!

[Adam Danz]

We can't run your code without having the 'data' data.

[Prakash Choudhary]

data(:,2) is x coordinates for N numbers

data(:,3) is y coordinates for N numbers

sir!!! you can consider random points and the code will give you the rectangle and line segments but the intersect part is not satisfying to me so i need help SOS!!!

[Adam Danz]

Yes, we could generate our own fake data to help you solve your problem. But there's always a risk that the data we generate in the dark aren't similar enough to your actual data and that leads to a lot of wasted time and a lot of unnecessary dialogue. So it's your responsibility to produce some kind of data for people to work with that reproduces the problem.

[Prakash Choudhary]

Yes sir but how can i attach the xlfile here i can just copy the coordinates here

[Adam Danz]

There we go; we can work with that. However,

• your 'data' matrix has 3 columns so we're missing a column of data
• We're also missing the value of 'D'.

[Prakash Choudhary]

Sorry for That The value of D=200 however i missed to mention that before

[Prakash Choudhary]

and the value of x2v,y2v however is same come from the rectangle one side lines

[Prakash Choudhary]

and thank you so much for your time sir !!!!!

[Adam Danz]

Ok, what about the 3rd column of 'data'?

" how can i show that the line x2v,y2v intersected by the rectangle"

x2v and y2v are both [20 x 2] matrices so they will produce two lines. And what rectangle do you expect those two lines to intersect?

I might be helpful to include an image of the intersection.

[Prakash Choudhary]

[Prakash Choudhary]

i atteched the picture which can help you to understand my situation for the rectangle intersect.

[Adam Danz]

I don't see any rectangles nor do I see any intersections.

Are you asking for the coordinates where the orange vertcial line that is circled and labeled "2" would intersect the blue lines if it extended vertically?

I can't help without reproducible code and that still hasn't been provided.

[Prakash Choudhary]

yes i want to know that coordinates where it overlaps/ intersect the 2 or 3 by 1

[Prakash Choudhary]

if possible can you improvise the code as you want

[Prakash Choudhary]

and its more like a polyshape object i consider as a rectangle because it made of a four different points

[Adam Danz]

I can't do anything until I have inputs that reproduce the problem. You could attach a mat file using the paperclip icon. The mat file should contain all input variables.

[Prakash Choudhary]

is it possible to chat with you through email?

[Adam Danz]

The solution probably isn't that complicated. You have to find the x value of the vertical lines; then, given that x value, find the y value on the blue line (interpolate if needed). The solution probably would have taken less time to write than the time spent going back and forth trying to understand your data. There has already been 20 comments on this and still, no data. We could exchange comments for the next few months and I still won't be able to help until you attach some data for me to work with.

You already produced a figure. That's impossible to do without data. So you have the data. You just need to save it to a mat file and attach it. Unfortunately I have other obligations today but I might have time to help you later (if there are data to work with).
