Ray, I never grew fond of Object Oriented Programming in Matlab, it seemed a little forced just to follow the OOP crowd. The last time I used OOP in Matlab was 10 years ago, it probably matured by now.
As for my "problem", I was just curious if I was doing something dumb. I just need to save mpc v2 data, and that can be done easily in different ways. I'll try your suggestion, it seems to be the most straight forward solution.
