Hello people,
I'm trying to graph the traditional sphere equation or let's say in more general a 3D ellipse. The problem is that I'm failing to graph it using the function "surf", here's the script I'm using:
function SurfaceGraph(a,b,c,N,M)
t=(0:N)*2*pi/N;
u=(0:M)*pi/M;
x=a*cos(t).*sin(u);
y=b*sin(t).*sin(u);
z=c*ones(N+1).*cos(u);
surf(x,y,z);
end
and I'm calling the function: SurfaceGraph(1,1,1,100,100), the error I'm getting is about the matrices dimensionality.
I'm aware that the function "sphere" is there, that I can use for graphing spheres, but actually my purpose of this script is visualising different polyhedra through different discretisation of the angles t and u.
Please tell me how I can graph these parametric equations, any effort is appreciated.
Thanks
