All my variables are interdependent. How do I pass extra variables for Ode and algebraic equations?

Well, the error says it all, you don't define EVI in the function trial.m, it's not passed in as a variable anywhere, and its not declared as a global. Therefore you get an error EVI not defined. Same for VI.
See the docs on ode45 etc. for the standard method of how to pass in extra variables to the ode solvers.

By the way, you should have left the question as it was, now others looking up the same question won't understand the answer. Start a new question for a new (better defined) problem.
