Warnings
Message Identifiers
Use a message identifier argument with warning to attach a unique tag to
that warning message. MATLAB uses this tag to better identify the source of
a warning. The first argument in this example is the message identifier.
warning('MATLAB:paramAmbiguous', ...
'Ambiguous parameter name, "%s".', param)
See “Warning Control Statements” on page 8-17 for more information on
how to use identifiers with warnings.
Identifying the Cause
The lastwarn function returns a string containing the last warning message
issued by MATLAB. You can use this to enable your program to identify the
cause of a warning that has just been issued. To return the most recent
warning message to the variable warnmsg, type
warnmsg = lastwarn;
You can also change the text of the last warning message with a new message
or with an empty string as shown here.
lastwarn('newwarnmsg');
lastwarn('');
% Replace last warning with new string
% Replace last warning with empty string
