Draw the function y =exp (−x2) cos (20x) in the range x =− 2:0.1:2. All axes should belabeled and a title included. Compare the results of using the functions fplot and plot to plot this function. 1.10. Write a MATLAB script to draw the functions y = 3sin (πx) and y = exp (−0.2x) on the same graph for x =0:0.02:4. All axes should be labeled. Use gtext to label one of the several points of intersection of the graphs. Use the functions meshgrid and mesh to obtain a three-dimensional plot of the function
Z = 2xy/ (x2+y2) for x = 1:0.1:3 and y =1:0.1:3
Redraw the surface using the function surf, surfl, and contour.
