Extend generic class along with imported data

[vecchp]

I'm not exactly sure if the terminology I'm going to use is correct so bare with me.

I have a generic equation and I want to create two specified instances. However I have data that is loaded and I want to be able to access it from both specified instances. I don't want to make a copy of the data for every new instance of the equation, I want to inherit it . I was thinking of creating a generic class and extending it but that doesn't solve the issue of loading the data. Does anyone have suggestions on how to accomplish this?


I've attached a diagram of what I'm talking about
