I calculate the minimum point on my surface consisting of the X, Y and Z axes. I want to show this calculated point on the Figure as well. I can select the point with the mouse, but it is quite difficult. How can I show this point in my figure?

Ran in:
[X,Y,Z] = peaks(100) ;
[val,idx] = max(Z(:)) ;
surf(X,Y,Z) ;
shading interp
hold on
plot3(X(idx),Y(idx),Z(idx),'+r')
