Create a UML class diagram of all existing classes/functions in the current MGM2D library

• To better aid development and translation to python, I need a class diagram of the existing Matlab and C++ codebase.
• The UML diagram should have all classes and functions labeled with variables, objects, and dependencies labeled.
• Consider clarifying the class diagram model: Since Matlab uses functions and classes nearly interchangeably, it may be more clear to have a box for every function not only just classes.
• Consider also creating an activity diagram or flowchart of behavior to aid in visualizing the logic flow in the code.

Researched some UML drafting software. PlantUML is a text based UML drafting language that will work. A PlantUML text document as well as the UML image that it creates will be placed in the /docs/ folder.

The simplified model on the project plan shows a basic flowchart of data behavior. During our code walkthrough, Dr. Grady Wright also advised to show the interpolator operators in the preprocessing phase.
