Using MatLab, I know how to create a line segment connecting two points using this code:
line([0 1],[0 1])
This draws a straight line segment from the point (0,0) to the point (1,1).
What I am trying to do is continue that line to the edge of the plot. Rather than just drawing a line between these two points I want to draw a line through those two points that spans the entire figure for any set of two points.
For this particular line and a x=-10:10, y=-10:10 plot I could write:
line([-10 10], [-10 10]);
But I would need to generalize this for any set of points.
