str1 = ('rabbit is eating grass near a tree');
str2 = ('rabbit is sleeping under tree');
str=intersect(strsplit(str1),strsplit(str2))
OR, to maintain the order
str=intersect(strsplit(str1),strsplit(str2),'stable')

This works in MATLAB versions prior to R2013a:
>> str1 = ('rabbit is eating grass near a tree');
>> str2 = ('rabbit is sleeping under tree');
>> w1 = regexp(str1,'\S+','match');
>> w2 = regexp(str2,'\S+','match');
>> intersect(w1,w2)
ans =
is
rabbit
tree
