2 MATLAB/Octave 3D Graphics 1. Plot the following function x,y) = (x Both axis should go from -2.5 to 2.5. Use the functions meshgrid and mesh. 2. Use the function view and rotate3d to change the viewpoint. 3. Generate a contour plot of f(x, y) using countour. 4. Generate plots of f(x, y) using surf, meshc, meshz, and waterfall 5. Generate plots of f(x, y) using surfl with a colorbar colorbar for different color-maps (e.g. colormap bone.) 6. Issue the command logo to generate a figure with the MATLAB logo. View the Logo m-file and experiment with the visualization commands in MATLAB. Try cameramenu
