1.6 Controlling output

After you start writing longer scripts and programs, you will find that often MATLAB's output scrolls off the screen, forcing you to use the mouse to scroll back to see the beginning of the output. You can force MATLAB to show just one screenful at a time by typing more on. (Unix savvy readers will recognize more as well.) Try typing more on then type help elfun. Hit the space bar to see successive screens. MATLAB's precision when doing computation is about 15 digits. The format command decides how many digits are shown and in which format. Try the following and see how pi is displayed for each setting.
