i am trying to figure out a way to give equality constraints to my multiobjective genetic algorithm i searched over a lot of examples...but i couldnt find anything which have EQUALITY CONSTRAINTS.
if someone could send an example. that would be really helpful thanks in advance

Same way as for ga() or fmincon: use the Aeq and beq parameter positions for linear equality, use the nonlcon for nonlinear equality.
Note that you might have difficulty if you are trying to use Aeq and beq together with integer constraints. The trick to doing that is to not tell ga or gamultiobj that you are using integer constraints and instead use the options to specify generation and mutation and recombination functions that just happen to always return integers in those positions.
