The Description of symvar says: symvar 'expr' searches the expression, expr, for identifiers other than i, j, pi, inf, nan, eps, and common functions. symvar displays those variables that it finds or, if no such variable exists, displays an empty cell array, {}.

edit symvar
Look at the comment inside the symvar.m that says:
Find opening parentheses and check to make sure they don't trail a variable. If one does, it is a treated as a function name and removed from b and e.

Does that mean that it eliminates variables that have been indexed, if the user used '()' indexing?
