How do I print a 1-inch by 1-inch square on a piece of paper?

I have been searching the help files and MATLAB Answers but my pictures are still coming out distorted.

Look at Figure Properties for PaperSize and PaperSizeMode and PaperUnits

Then construct whatever graphics you want on an axes whose Units has been set to 'inch' and with appropriate Position, and with DataAspect set to [1 1 1]; with that combination, a change of 1.0 in your data will correspond to 1.0 inch

So I tried:

x=[0,0,1,1,0];
y=[0,1,1,0,0];
plot(x,y) 
drawnow
set(gca,'xlimmode','manual','ylimmode','manual')
set(gcf,'units','inches')
set(gcf,'papersize',[8.5,12])%width height
set(gcf,'paperpositionmode','manual');
set(gcf,'paperposition',[2,2,1,1]);%distance from left, distance from bottom, width, height.
daspect([1,1,1]);
axis off
print
print(gcf,'-dpng','-r0','test.png')
winopen('test.png')

The square is about 5/8" x 5/8" when printed and the saved image is showing a buffer around the square, which could be causing the square to be smaller than 1" x 1". How do I remove the buffer?

[Walter Roberson]

fig = figure('Units', 'inches', 'papersize', [8.5,11], 'paperpositionmode', 'auto');
ax = axes('Units','inches', 'Position', [1 1 1 1])
x=[0,0,1,1,0];
y=[0,1,1,0,0];
plot(ax, x, y)
set(ax, 'visible', 'off', 'dataaspectratio', [1 1 1]);
print(fig)

Tested on my system. Interestingly the square did not show up as 1" x 1" on my display, but printed out as 1" x 1" to within the accuracy of my measuring tape.
