Create and plot an ellipsoid with a center at (0, –0.5, 0) and semiaxis lengths (6, 3.25, 3.25). Use axis equal to use equal data units along each coordinate direction.

ellipsoid(0,-0.5,0,6,3.25,3.25)
axis equal

Generate coordinates of an ellipsoid with a center at (0, 0, 0) and semiaxis lengths (1.5, 1.5, 3).

[X,Y,Z] = ellipsoid(0,0,0,1.5,1.5,3);

Create a surface plot of the ellipsoid.

surf(X,Y,Z);
axis equal

Plot a second ellipsoid with its center translated by (3, 0, 5) from the first ellipsoid. To be able to rotate the second ellipsoid in the next step, return the surface object as s.

hold on
s = surf(X+3,Y,Z+5);

Rotate the second ellipsoid by 45 degrees around its $$x$$-axis. The new coordinates of the translated and rotated ellipsoid are stored in s.Xdata, s.Ydata, and s.Zdata.

direction = [1 0 0];
rotate(s,direction,45)

Display ellipsoids with center coordinates (0, 0, 0) and semiaxis lengths (2, 1, 1) with different number of faces.

Call the tiledlayout function to create a 2-by-2 tiled chart layout. Call the nexttile function to create the axes. Then, use the ellipsoid function to plot three ellipsoids with different numbers of faces. Plot the ellipsoids in different tiles of the chart by specifying the axes.

tiledlayout(2,2);
ax1 = nexttile;
ellipsoid(ax1,0,0,0,2,1,1)
axis equal

ax2 = nexttile;
ellipsoid(ax2,0,0,0,2,1,1,50)
axis equal

ax3 = nexttile;
ellipsoid(ax3,0,0,0,2,1,1,80)
axis equal
