i have a 3 2dimension data.
x(100x100)
y(100x100)
z(100x100)
i want 3 dimension data. like MRI data.
data(100x100x100);
example code
R=5;
r=1;
u=linspace(0,2*pi,100);
v=linspace(0,2*pi,100);
[u,v]=meshgrid(u,v);
x=(R+r.*cos(v)).*cos(u);
y=(R+r.*cos(v)).*sin(u);
z=r.*sin(v);
figure(1)
mesh(x,y,z);
x,y,z to data(100x100x100)
pliz help me

Hi,
As mentioned by darova, it is not possible to create the 3D data. The u v are the corrdinate matrices which are used to calculate the x,y and z values. These x,y,z values correspond to the values of the functions that were used to calculate them at that particular corrdinate. This information cannot be stacked up to from a 3D martix(as because the info you have is of the surface).
In simple terms, you have information of around 30000 points and to create the data you need 1000000 points.
Hope this explains!
