MATLAB: Find common words in 2 strings

strings

i have 2 string

str1 = ('rabbit is eating grass near a tree');
str2 = ('rabbit is sleeping under tree');

In these 2 strings 'rabbit' 'is' 'tree' is common…. How can i find the common words present in 2 strings….

i want result

str = 'rabbit' 'is' 'tree'

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')

How about using regexp to find the position of spaces, and delete 2nd~Nth spaces? Like:

mystring = 'this is my string';
pos = regexp(mystring,'\s');
mystring(pos(2:end)) = [];

Loop not required, just use indexing:

Method one:

>> str1 = 'Hello';
>> str2 = 'Canada';
>> strN = [str1,str2];
>> strN([2:2:end,1:2:end]) = strN
strN = CHaenlaldoa

Method two:

>> strN = str2([1,1],:);
>> strN(1,2:end) = str1;
>> strN = strN(2:end)
strN = CHaenlaldoa
