Hey L54,
Unfortunately, there have not been any public announcements regarding the support of object-oriented code for the MathScript RT nodes. Also, for tips on how to change your code to make it work, there really is no easy way to go about doing this.
Are you deploying to a RT target? Would it be possible for you to use the MATLAB Script Node? This is included with LabVIEW and actually connects to your MATLAB software and would most likely be able to run the object-oriented code.
Sorry about not supporting object-oriented code, but hopefully using the MATLAB Script Node help you achieve your desired functionality.
