Export to PDF that uses entire page

I'm trying to output results of simulations -- saveas(gcf, ['samplefilename.pdf']) -- to a PDF, but it seems like Matlab is forcing me to only use the middle half of the page. Can you please point me in the right direction on how to set up a figure so that it fills the page? (Could I change the aspect ratio to match US Letter size and Matlab will automatically expand the figure to fill the page?) Thanks so much for any help.

You might be able to do it using print
