Finding specific TF2 values and return XY

ROOT
1

Hello,

I found TF2::GetMinimumXY() and TF2::GetMaximumXY(), but I am looking for a method to find specific values. Is there any way to get like TF1::GetX() but using TF2?
Something like TF2::GetXY ?

Cheers,
M.

Dear @meyerma ,

Probably @moneta should know better, but just looking at the TF2 docs I don’t see a method like the one you are looking for unfortunately.

Hello,
There is no TF2::GetXY, because the solution for a multi-dimenisional function is not a single point but a set of values, i.e a contour line. The simplest way to do this is evaluating the function in a grid and then from the grid find the desired contour level.
