surface 3d plot

good afternoon sir

I got 3d plot like below form with my code

[gm,km] =meshgrid(0.1:0.01:0.5,0.1:0.01:0.5);

R2 = gm.*(7.5581+ (0.0813+km)./(0.1129+km));

surf(gm,km,R2)

colorbar

xlabel('β','fontweight','bold','fontsize',14);

ylabel('λ_u','fontweight','bold','fontsize',14);

zlabel('R_0','fontweight','bold','fontsize',14);

I requesting you sir please tell me how to get the 3d plot like below graph model.by using above code

[gm,km] =meshgrid(0.1:0.01:0.5, 0.1:0.01:0.5);
% 1st surface
R2 = gm.*(7.5581+ (0.0813+km)./(0.1129+km)); 
surf(gm,km,R2, 'EdgeColor', 'none')

hold on
% 2nd surface  [you must prode the equation
R0 = ones(size(gm));
surf(gm,km,R0, 'EdgeColor', 'none')

surf(gm,km,2*R0, 'EdgeColor', 'none')

colorbar
xlabel('β','fontweight','bold','fontsize',14);
ylabel('λ_u','fontweight','bold','fontsize',14); 
zlabel('R_0','fontweight','bold','fontsize',14);
