Scripts are used for several different purposes in MATLAB. In some cases, such as for examples, a script is a standalone file that runs by itself. In other cases, scripts are used to initialize variables in functions or other utility tasks. The messages appropriate for one style of script are not always appropriate for the other.

Code Analyzer has found a variable in a script that the script appears to use, but not set. This might represent a problem in a standalone script, but be acceptable in other kinds of scripts. This message is off by default, but can be enabled, as appropriate.

If this message has detected a problem in the script, fix the problem. Otherwise, suppress the message on this line, for the entire script. Or, if you commonly do this kind of coding, leave the message disabled in your default Code Advisor preference settings, as described in Adjust Code Analyzer Message Indicators and Messages.
