I need an optimvar to be zero when another optimvar is zero

I have a problem with three varibles:

x = optimvar('x',NumSitiPot,NumSitiUtenti,'Type','integer','LowerBound',0,'UpperBound',1); 
y = optimvar('y',NumSitiPot,'Type','integer','LowerBound',0,'UpperBound',1); 
w = optimvar('w',NumSitiPot,NumSitiUtenti,'LowerBound',zeros(NumSitiPot,NumSitiUtenti),'UpperBound',ones(NumSitiPot,NumSitiUtenti)); 

and I need w(i, j) to be zero when x(i, j) is zero

Impose the constraint w<=x.
