To make your code more robust, check for edge cases and problematic
conditions. The simplest approach is to use an
switch statement to check for a specific condition,
and then issue an error or warning.
allow you to catch and respond to any error.

|Execute statements and catch resulting errors|
- Issue Warnings and Errors
To flag unexpected conditions when running a program, issue a warning. To flag fatal problems within the program, throw an error. Unlike warnings, errors halt the execution of a program.
- Suppress Warnings
Your program might issue warnings that do not always adversely affect execution. To avoid confusion, you can hide warning messages during execution by changing their states from
- Restore Warnings
You can save the warning current states, modify warning states, and restore the original warning states. This technique is useful if you temporarily turn off some warnings and later reinstate the original settings.
- Change How Warnings Display
You can control how warnings appear in MATLAB®, including the display of warning suppression information and stack traces.
- Use try/catch to Handle Errors
try/catchstatement to execute code after your program encounters an error.
- Clean Up When Functions Complete
It is a good programming practice to leave your program environment in a clean state that does not interfere with any other program code.
