Hello, I've plot 5 lines on the same graph with their edge coordinates. Now, I wish to find the intersection point coordinates (xi, yi) from any 2 intersecting lines specifically. Example: Intersection point between bottom slanting line and horizontal straight line.I used polyxpoly function, but it's not working…Is there any better way to do this?. Thank you.
%Bottom slanting line
x1=[1000,1];y1=[1E-8, 1E-5];loglog(x1,y1)hold on%Top slanting line
x2=[1,3000];y2=[1E-3,3.5E-7];loglog(x2,y2)hold on%First vertical straight line
x3=[1000, 1000];y3=[1E-9, 1E-6];loglog(x3,y3)hold on%Second vertical straight line
x4=[3000,3000];y4=[3.5E-7,1E-9];loglog(x4,y4)hold on%Horizontal straight line
x5=[1,5000];y5=[3.98E-7,3.98E-7];loglog(x5,y5)%Find intersection point
[xi,yi]=polyxpoly(x1,y1,x5,y5)mapshow(xi,yi,'DisplayType','point','Marker','o')
