CountMember

Count members.

Description

C = COUNTMEMBER(A,B) counts the number of times the elements of array A are present in array B, so that C(k) equals the number of occurences of A(k) in B. A may contain non-unique elements. C will have the same size as A.
A and B should be of the same type, and can be cell array of strings.
 
Examples:
      countmember([1 2 1 3],[1 2 2 2 2])
         -> 1 4 1 0
      countmember({'a','b','c'},{'a','x','a'})
         -> 2 0 0

Excellent. It could be better if you can also return the logical index as a second output.
