Plot drawn figure fitting or not fitting, no expression, is the only curve, and then how to two points determine the intersection of straight line and the curve? Intersection is more, there are thousands of, use the cursor coordinates are not realistic, click on the node
I use y (I) said that the points on the curve, expressed in v (I) value at a point on the line, iterate over x determine a coordinate x (I), for example, if y (I) - v (I) than the absolute value of y (I) - v (I - 1 or I + 1) the absolute value of a little boy, I judge this is the intersection point, finally found that doesn't work,,,,
What should do excuse me
