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 view(3)
