Finding intersection points in a square.

Hello,

Is there good way to find the intersection points in a square.

Also, can I get intersection points between the lines?

I spent pretty much time but cannot solve it. (I am practing MATLAB now)

Please help me..

Yes, you can use,

https://www.mathworks.com/matlabcentral/fileexchange/93470-intersections-of-multiple-2d-lines-or-line-segments

square=polyshape([0 0; 0 1; 1 1; 1 0]);
line=[0.01,1,-0.6];

out=linexlines2D(square,line) %intersections

out = 2×2

0 1.0000 0.6000 0.5900

plot(square) 
hold on
 fimplicit(@(x,y) [x(:),y(:),x(:).^0]*line(:));

Warning: Function behaves unexpectedly on array inputs. To improve performance, properly vectorize your function to return an output with the same size and shape as the input arguments.

 plot(out(1,:),out(2,:),'o','MarkerFaceColor','r');
hold off
xlim([-1,2])
axis equal
