fmincon - How to suppress warnings during gradient estimation?

Fmincon estimates the gradient numerically. While doing so it sometimes gets close to the parameter bounds which causes my objective function to invert a lot of nearly singular matrices (and produce the respective warning).
How can I suppress warnings during numerical compuation of the gradient with the fmincon solver?

To suppress warnings you first need the warning ID. To get the ID, run these two lines right after receiving the warning.
w = warning('query','last')
id = w.identifier;
Then you can turn it off, run the code, and turn it back on.
warning('off',id)
% code
warning('on',id)
Note that if your code is stopped prior to tuning it back on, obviously it won't be turned back on. Some people use try/catch to get around that.
