Highligh a curve from a 3D plot

Hello,

I would like to highlight a curve (representing the maximum values of the curves) that is part of a 3D plot. I attach one picture for a reference (my objective is to obtain something like the red thick displayed in the figure).

Try something like this:

v = -1:0.1:1.2;                                                     % Create Data
[X,Y] = ndgrid(v);                                                  % Create Data
Z = exp(-(X.^2-Y.^2));                                              % Create Data

[zmax,idx] = max(Z,[],2);                                           % Find Maximum (Choose Dimension)

figure
surf(X, Y, Z)
hold on
plot3(v, ones(size(v))*max(v(:)), zmax, '-r', 'LineWidth',2.5)
hold off
grid on

producing (for these values):
