the point that I want to add to my figure is: x=70.00; y= 0.30. Thanks for your time.

Ran in:
Probably the easiest way —
figure
% surf(...)
% view(0,90)
hold on
plot3(70.00, 0.30, 1, 'sr', MarkerFaceColor='r')
hold off
view(0,90)
Ax = gca;
Ax.YScale='log';
You can also vary the MarkerSize and other properties.
Since you are plotting on a surface, it may be necessary to use the scatteredInterpolant function to put the point exactly on the surface, or just use the maximum value for the surface (apparently 1, according to the colorbar scale), as I did here.
EDIT — Added explanatory detail.

@Adnan, there is also drawpoint and a set of other associated functions for other "draw" functions that you may want to check out, though I agree that plot() is certainly the easiest way.
