I'm assuming you're looking for a numerical solution for t given numeric values for y and m. (E.g., if y = 1 and m = 2, find a t that satisfies the equation.)
Fzero solves scalar equations in one unknown. Type "doc fzero" at the MATLAB prompt to see an example.
If you get errors, please post the specific errors you're getting, and the code that calls fzero.
