JSlider changeEvent and Matlab

[A Watcher]

I am working on a project that combines Matlab and Java. I have a
JSlider and a Matlab function is triggered when it's value is
changed. The only problem is that the code is in an infinite loop.
The JSlider is in a JPanel that is in turn embedded in a Matlab
panel. The function runs, exits and is then called endlessly. Is
there a method that I can use to unset the changeEvent value for the
slider?

Thanks
