Creating the MATLAB Logo

This example shows how to create and display the MATLAB® logo.

Use the membrane command to generate the surface data for the logo.

L = 160*membrane(1,100);

Create a figure and an axes to display the logo. Then, create a surface for the logo using the points from the membrane command. Turn off the lines in the surface.

f = figure;
ax = axes;

s = surface(L);
s.EdgeColor = 'none';
view(3)

Figure contains an axes. The axes contains an object of type surface.

Adjust the axes limits so that the axes are tight around the logo.

ax.XLim = [1 201];
ax.YLim = [1 201];
ax.ZLim = [-53.4 160];

Figure contains an axes. The axes contains an object of type surface.

Adjust the view of the logo using the camera properties of the axes. Camera properties control the view of a three dimensional scene like a camera with a zoom lens.

ax.CameraPosition = [-145.5 -229.7 283.6];
ax.CameraTarget = [77.4 60.2 63.9];
ax.CameraUpVector = [0 0 1];
ax.CameraViewAngle = 36.7;

Figure contains an axes. The axes contains an object of type surface.

Change the position of the axes and the x, y, and z aspect ratio to fill the extra space in the figure window.

ax.Position = [0 0 1 1];
ax.DataAspectRatio = [1 1 .9];

Figure contains an axes. The axes contains an object of type surface.

Create lights to illuminate the logo. The light itself is not visible but its properties can be set to change the appearance of any patch or surface object in the axes.

l1 = light;
l1.Position = [160 400 80];
l1.Style = 'local';
l1.Color = [0 0.8 0.8];
 
l2 = light;
l2.Position = [.5 -1 .4];
l2.Color = [0.8 0.8 0];

Figure contains an axes. The axes contains an object of type surface.

Change the color of the logo.

s.FaceColor = [0.9 0.2 0.2];

Figure contains an axes. The axes contains an object of type surface.

Use the lighting and specular (reflectance) properties of the surface to control the lighting effects.

s.FaceLighting = 'gouraud';
s.AmbientStrength = 0.3;
s.DiffuseStrength = 0.6; 
s.BackFaceLighting = 'lit';

s.SpecularStrength = 1;
s.SpecularColorReflectance = 1;
s.SpecularExponent = 7;

Figure contains an axes. The axes contains an object of type surface.

Turn the axis off to see the final result.
