Question

y in the blank lines provided below, insert the approprilate commands) needed to complete the fgure. x1 - linspace (0, 4, 25) Y1 linspace(0, 3, 25); G(ii) a)Generate a possible script file using appropriate sequence of cylinder, surf, title etc commands to develop a MATLAB script that will generate the 3-d graphics image shown. This figure was obtained using cyfinder function ais b)What does 'a and 'b' stand for in the command viewla,b). What will be the view () commands to obtain the side view shown below Ths Sigurewas obtained using cylinder Sucton

Answer 1

Program 1

X1 = linspace(0, 4, 25); Y1 = linspace(0, 3, 25); [X,Y] = meshgrid(X1,Y1); Z = X.^2 + Y.^2; figure surf(X,Y,Z)

OUTPUT

Program 2 (part a, part b)

radius = 5; height = 2; N = 50; [X,Y,Z] = cylinder([0 radius], N); % Plotting the upper part figure surf(X,Y,Z*height) % plotting the lower part hold on surf(X,Y,-Z*height) axis square hold off xlabel('x') ylabel('y') zlabel('z') pause(3) % View part b a = 0; b = 0; view(a,b)

OUTPUT

Program 3

rectangle('Position', [6,1,2,2]) hold on plot([8 6], [1 3], 'k') plot([6 8], [1 3], 'k') tri_points_x = [6,7,8]; tri_points_y = [3,4,3]; fill(tri_points_x, tri_points_y, 'k') axis([4 10 -1 6]) hold off grid on xlabel('X-AXIS') ylabel('Y-AXIS') title('2-D Graphics') text(7, 4.5, 'Roof') text(7, 0.5, 'Base') hold off

OUTPUT

4 3 2 2 5 503 -2 5 -5 5 5 251 0 5 2 2-D Graphics Roof 4 2 Base 4 6 10 X-AXIS
