ellipsoid equation is x^2 +y^2 +2z^2 =10

Try this (partially copied from the documentation page Connecting Equal Values with Isosurfaces):
x = linspace(-10, 10, 50);
[X,Y,Z] = meshgrid(x);
V = (X.^2 + Y.^2 + 2*Z.^2);
figure
hp = patch(isosurface(X,Y,Z,V,10))
isonormals(X,Y,Z,V,hp)
hp.FaceColor = 'r';
hp.EdgeColor = 'none';
camlight left;
lighting gouraud
grid on
view(-20,30)

Also see the documentation on the isosurface function.

You can also use,
https://www.mathworks.com/matlabcentral/fileexchange/87584-object-oriented-tools-for-fitting-conics-and-quadrics
which has the convenience of letting you specify yaw/pitch/roll angles for the ellipsoid.
[Center,ABC,YPR]=deal([0 2 1] , [6 2 1], [60 40 0]); %center, radii, yaw/pitch/roll
obj=ellipsoidalFit.groundtruth([],Center,ABC,YPR);
plot(obj, {'FaceColor', 'm'});
xlabel X; ylabel Y; zlabel Z
