I have a variable x that is of class symfun and I want to convert it to class sym. Unfortunately I can't post the code because there are a ton of custom functions. I found that the code x=x(1,1) works when x is a two dimensional vector but that is not always the case.

Symfun is a subclass of sym, so, yes, a symfun is already a sym.
To get only the body of the function, use formula or call the symfun:
syms x(t)
x(t) = t^2 - t;
formula(x)
% or:
x(t)
