z=1-x^2,z=0,y=0,y=3

Answer 1

[madhan ravi]

[x y] = meshgrid(-1:0.1:1); % Generate x and y data
z = 1-x.^2; % Generate z data
surf(x, y, z) % Plot the surface
hold on
[x y] = meshgrid(-1:0.1:1); 
z = zeros(size(x, 1));
surf(x, y, z)
[x z] = meshgrid(-1:0.1:1);
y = zeros(size(x, 1)); 
surf(x, y, z) 
[x z] = meshgrid(-1:0.1:1);
y = 3*ones(size(x, 1)); 
surf(x, y, z) 
xlabel('x')
ylabel('y')
zlabel('z')
