% plot y vs. x

set(gcf, 'PaperSize', [w h]);           % set size of PDF page
set(gcf, 'PaperPosition', [0 0 w h]);   % put plot in lower-left corner
print ('-dpdf','plot04.pdf');           % save plot as pdf file

This example demonstrates how to save a plot to a pdf file. The variables h and w hold the height and width of the plot (in inches). The command set(gcf, 'PaperSize', [w h]) defines the size of the pdf file and the command determines where on the pdf file the plot will appear. The final command print ('-dpdf','plot04.pdf') saves the plot to a file called 'plot04.pdf'. The command print is a bit of a misnomer, since it doesn't actually print anything to a physical printer. It just saves the file.

Matlab can save plots in many different file types. Here are a few more possibilities:

print ('-dpdf','test.pdf');     % PDF file (vector)
print ('-deps','test.eps');     % Encapsulated Postscript B&W (vector)
print ('-depsc','test.eps');    % Encapsulated Postscript color (vector)
print ('-dtiff','test.tiff');   % tiff file (bitmap)
print ('-djpeg','test.jpg');    % JPEG file (bitmap)
