Plot parameters
For example:

plot(Wj(:,1),Wj(:,2),'o')
for i = 1:size(Wj,1)
   text(Wj(i,1),Wj(i,2),attrib(i,:))
end
title('Attribute loadings')

figure
plot(T(:,1),T(:,2),'o')
for i = 1:size(T,1)
   text(T(i,1),T(i,2),num2str(i))
end
title(' Score plot')

figure
for j=1:4
  subplot(2,2,j)
  plot(T(:,j),U(:,j),'o')
  for i = 1:size(T,1)
     text(T(i,j),U(i,j),num2str(i))
  end
  title([' T/U plot - comp: ',num2str(j)])
end
