Hi All,
Suppose we have a set of 2D points:
px = [1, 2, 5];
py = [1, 2, 1.5];
When we plot these points, we get 3 distinct points:
plot(px, py, 'r*')
Is it possible to draw a line connecting any two of those directly on the figure and measure the Euclid distance between them?
Regards
Edit
I don't need to PLOT a line. I need to click at one point and move the mouse to the second point to draw the line and measure the Euclidean distance between them,.

px = [1, 2, 5];
py = [1, 2, 1.5];
x = [px(1) py(1)] ;
y = [px(2) py(2)] ;
z = [px(3) py(3)] ;
plot3(x,y,z,'r')
d = sqrt(diff(x)^2+diff(y)^2+diff(z)^2)
