Error Handling<br />
In many cases, it is desirable to take specific actions when different kinds<br />
of errors occur. For example, you may want to prompt the user for more<br />
input, display extended error or warning information, or repeat a calculation<br />
using default values. The error handling capabilities in <strong>MATLAB</strong> let your<br />
application check for particular error conditions and execute appropriate code<br />
depending on the situation.<br />
