Can I get he frequency of each value in a vector without a loop?

I have a vector which contains discrete values and I want to know hte frequency of each value. I have managed to get the result using a loop but I was wondering if it is possible to speed to process up.

aa=floor((10*rand(10,1)))*10 UniqVal=0:10:100; cat = length(UniqVal); bb=zeros(1,cat); for k=1:cat bb(k)=sum(aa==UniqVal(k)); end
