How can I make a solid triangular prism?

figure(1)

v = [0 0 0; 5 5 0; 0 5 0; 0 0 2; 5 5 2; 0 5 2];

f = [1 2 5 4; 2 3 6 5; 1 3 6 4];

axes('XLim',[-7 7],'YLim',[0 5],'ZLim',[0 2],'XDir','reverse','YDir','reverse'); view(3);

patch('Faces',f,'Vertices',v,'FaceAlpha',0);

This generates an outline, what is the best way to modify it to make a solid shape?
