| Oct 4, 2016 at 15:24 | comment | added | Michael E2 | Just how do you want to use the "numerical intersection"? I don't see the purpose in having a few scattered points to very high precision. (1) For plotting, increasing precision beyond a few digits does not improve the image. (2) Given a point close the curve, should one keep x or y fixed in trying to improve its position, or should one move parallel to the gradient or some other direction? Your example fixes x, but that seems arbitrary and inappropriate for all possible curves. | |

| Oct 3, 2016 at 18:40 | comment | added | Kagaratsch | @march Thank you, this helped me alot! I adopted the solution in this link to my case, with a few tweaks. Since I need a lot of precision, I'll post my tweaks below in case if others might be interested. | |
| Oct 3, 2016 at 18:13 | comment | added | march | You can extract the points from the plot and refine them using FindRoot. See, for instance, here. This is actually a pretty common method; there should be many examples of this on this very site. | |
