Hi,

I have 2-d plot that is based on data (two vectors) and a horizontal line function (using fplot).

I am trying to find intersection point of outer most line of 2-d plot(blue) and red line, in other words I want to get the intersection point where red line hits the first and the last. Then I want to find difference between intersection points of x axes, that is x2 - x1. How should I proceed?

Thank you
