Help using lastwarn.m

I have code which does:
[msgstr, msgid] = lastwarn;
warning('OFF', msgid);
dostuff(); %generates a waring message
warning('ON', msgid);
The problem with this is that I still get one waring message, as the last warn before dostuff() was called was a different message.
I dont want to turn all warnings off as this is slow.
I would have thought that I could hard code the warning I want to turn off, but this doesnt seem possible:
"Warning: Out of range or non-integer values truncated during conversion to character."
how can I use msgid to ensure I never see that warning when calling do stuff? (I dont want to fiddle with the GUI settings either).
thanks

If you are getting that warning, your code is very likely wrong. You should figure out why it is happening, and change your code to prevent those circumstances from arising. That might involve using a different data type, or using a cell array, or might involve using floor() or ceil() or fix() or round() so that it is only integral values that are submitted to char()

Yes, warnging('off','MATLAB:nonIntegerTruncatedInConversionToChar'); I've also updated the answer above.

You need to find out the corresponding id generated by dostuff. You can try to do this by first reset the warning state and then run dostuff and lastwarn
warning('');
dostuff();
[msgstr, msgid] = lastwarn;
warning('off',msgid);
