I would like to have a 2D plot along with a 3D surface or mesh plot - shown by the blue line I drew on the surface plot below. How do I get it?

Does this get you started?
% create figure
figure
% Generate data to make a surface
x = -1:0.1:1;
y = -1:0.1:1;
[X,Y] = meshgrid(x,y);
Z = X.^2 + Y.^2 - 1;
% visualize 3D surface
surf(X,Y,Z)
% Generate data to make line plot in plane z = minimumZValue
minimumZValue = min(Z(:));
t0 = linspace(0,2*pi);
x0 = .8*cos(t0);
y0 = .8*sin(t0);
% visualize line plot
line(x0,y0,minimumZValue*ones(size(t0)),'linewidth',2)
% Generate data to make line plot in plane x = minimumXValue
minimumXValue = min(X(:));
y00 = linspace(min(Y(:)),max(Y(:)));
% will be shifted to make z = minimumZValue the new z = 0
z00 = exp(-5*y00.^2);
z00 = z00 + minimumZValue; % comment this out to see effect
line(minimumXValue(ones(size(y00))),y00,z00,'linewidth',2,'color','r')
xlabel('x')
ylabel('y')
grid on
