Code adapted from this guide (link)
vert = [0 0 0;1 0 0;1 1 0;0 1 0;0 0 1;1 0 1;1 1 1;0 1 1];
fac = [1 2 6 5;2 3 7 6;3 4 8 7;4 1 5 8;1 2 3 4;5 6 7 8];
colormap(vert)
patch('Vertices',vert,'Faces',fac,...
'FaceVertexCData',vert,'FaceColor','interp')

This isn't working for me. It shows me a 2 dimensional fig.

Click on the little popup rotation tool above the upper right corner of the image and then click and drag in the image to rotate the cube.
