Display current Matlab variable qroots if deFned 2. Execute built-in Matlab command qroots if it exists 3. Execute qroots.m if it can be found in the Matlab search path (described below) Commands within the M-Fle have access to all variables in the Matlab workspace and all variables created by the M-Fle become part of the workspace. Commands themselves are not normally displayed as they are evaluated. Placing the echo on command in the M-Fle will cause commands to be displayed. The command echo off

Unformatted text preview: (the default) turns o± command display and echo by itself toggles the command echo state. You could repeatedly edit qroots.m , change the values of a, b, and c, save the Fle, then have Matlab execute the revised script to compute a new pair of roots. Matlab functions useful in M-Fles: Command Description disp(ans) Display results without identifying variable names echo [on|off] Control Command window echoing of script commands input(’prompt’) Prompt user with text in quotes, accept input until “Enter” is typed keyboard Give control to keyboard temporarily.
