Intersecting Two Lines with Varying Angle
显示 更早的评论
Hi all,
I want to plot two intersecting lines, the most important point of the part is the angle of intersection. The angle between the lines depend on
L = 15.24;
F = 5;
S =20;
D = 10.16;
R = 146;
theta = 2* atan(((L-F)*S) / (D*R))
As I change the variables above, the angle of intersection of two lines should change. The lines are just for visual their values in the x-y axis do not represent anything.
Thank you

So I understand you just want to plot two lines where there is a specific angle between them. If we take one line as line y=0, you could plot them as follows:
plot([-D*R D*R],[-(L-F)*S (L-F)*S])
axis([-1 1 -1 1]) % set axis limits, this shows 2 units on x and y axis and they have a 1:1 ratio
set(gcf,'Position',[100 100 400 400]) % This is to adjust the figure size with corresponding 1:1 ratio.
hold on, plot([-1 1],[0 0],'-k'), title(['theta = ' num2str(theta,'%.2f') ' radians']) %show angle in title
