Revolving a 2D profile around any axis

Hello, I'm trying to rotate a curve around the y - axis. The code is under:

figure

% Define our initial profile

t = 0:.01:1;

x = 2*pi*t + 1;

y = sin(2*pi*t) + 2;

plot(x,y);

figure

% We use the cylinder function to rotate and align

% with the z-axis, to produce a 3D solid

[X,Y,Z] = cylinder(y);

surf(X,Y,Z)

The problem is that the cylinder does not count the x coordinates from the 2D profile and only revolves the curve around the z - axis. Can anyone help?

The rotate function allows you to rotate a curve around any axis. To rotate the curve along y-axis, use the below code.

h = surf(X,Y,Z);
for i = 1:360
    rotate(h,[0 1 0], i);
    drawnow;
end
