labels = kron((1:3)',ones(24,1));
or
labels = reshape(ones(24,1)*(1:3),[],1);

>> labelsKP=KronProd({ones(2400,1), (1:3).'});
you can get even more compression. For comparison,
>> labels = kron((1:3)',ones(2400,1));
>> whos labels labelsKP
Name Size Bytes Class Attributes
labels 7200x1 57600 double
labelsKP 7200x1 19660 KronProd
