If you are saving the data from with an app callback function, then you just need to use save to save the data to a mat file.
If you are saving the data from outside of the app such as from the base workspace, then you need to first access the data. To do that, the data should be stored as an app property (see step-by-step guide) and you need the handle to you app. See Three ways to access your app handle. Once you have the app handle, you can easily access any property including the property that stores your data and can save it using save().
