Is there a way to search an array for each value in a vector and return how many of each entry were found?

Say I had an array a = [5,6,3;10,1,24;1,2,3] and a vector v =[1,3,5,7], and I wanted to search the array for each entry in the vector such that it would return the number of times each entry was found. e.g. in this case it should return [2,2,1,0]. Is there any way to do this?

This should work.

a = [5,6,3;10,1,24;1,2,3];
v =[1,3,5,7];

w=zeros(size(v));
for k=1:numel(v)
    w(k)=numel(find(a==v(k)));
end

sum(bsxfun(@eq,a(:)',v(:)),2)
