Perhaps, this is the way to go with sym expressions:
isAlways(A == B)
isAlways(cond) checks if the condition cond is valid for all possible values of the symbolic variables in cond. When verifying cond, the isAlways function considers all assumptions on the variables in cond. If the condition holds, isAlways returns logical 1 (true). Otherwise it returns logical 0 (false).
