I've drawn two curves in my program. The first is simply f[x]=x and the second is ListLinePlot based on high-precise data. I am searching for a way (exact function or more sophisticated method) to find the common points of these curves or at least the number of their intersections, using only the plot.
I'd like to inform that the function from which ListLinePlot data is derived is too complex to solve it analytically.
