I have attached two plots I would like to analyze. In both of these plots, I would like to find the vertical distance between most of the points (excluding the points that are left of the curves) and the curve. As in, for each point, I would like to imagine a vertical line extending from the point to the curve, and then find the length of this line. Ultimately, I would like to have produced two column vectors, a and b, for each of the two plots, and then create one final column vector, a^2+b^2.
Does anybody have any insight as to how to do this?
Please let me know if I could provide more helpful information as well.
