% comment on PaperPosition
% [a,b,c,d]
% (a,b) is the coordinate of the lower-left corner of the figure
% (a,b) = (0,0) is the lower-left corner of the paper
% (c,d) is the coordinate of the upper-right corner of the figure relative to the lower-left corner of the figure
% Therefore, c>=a, d>=b
% Full paper position would be [0,0,8.5,11] in inches
