How can I use quaternions to animate cube in MATLAB R2014a version?

This is the my code to draw cube..

function plot_3d_cube(theta,varargin) %%theta in radian

H=[0 2.5 0 2.5 0 2.5 0 2.5; 0 0 2.5 2.5 0 0 2.5 2.5; 0 0 0 0 2.5 2.5 2.5 2.5]; %Vertices of the cube
S=[1 2 4 3; 1 2 6 5; 1 3 7 5; 3 4 8 7; 2 4 8 6; 5 6 8 7]; %Surfaces of the cube
figure(1)
hold on
H1 = zeros(size(S,1),4) 
H2 = zeros(size(S,1),4) ;
H3 = zeros(size(S,1),4) ;
for i=1:size(S,1)    
    Si=S(i,:); 
   fill3(H(1,Si),H(2,Si),H(3,Si),'blue','facealpha',0.6)
end
axis equal, axis on, hold off, view(20,10)
