MATLAB: Orientation of ellipsoid

functiongraphicsMATLAB

Hello, I am using ellipsoid function to represent an ellipsoid graphically. The input list requires me to enter the coordinates of the centre of ellipsoid and its semi-axes. There is no input for the orientation of the axis of the ellipsoid with respect to the coordinate system. Is there any way, this can be incorporated if my ellipsoids are at angle with respect to x, y and z axis.

See the help for the ROTATE function.
For example:
[x, y, z] = ellipsoid(0,0,0,5.9,3.25,3.25,30);
S = surfl(x, y, z);
colormap copper
axis equal
xlabel('X')
ylabel('Y')
zlabel('Z')
pause %  Push return to see the rotation take place.
rotate(S,[0 0 1],45)
