is something like this what you want
d ={'A' 'B'
'hello' 'hi'
'enter' 'exit'
'me' 'you'
'love' 'hurt'
'what' 'how'};
% str1={'hello' 'me' 'what'};
%Edit
str1='hello me what';
str1=regexp(str1,' ','split');
check=ismember(str1,d); %use d(:,1) to check only first column
if sum(check)==3
output=1
else
output=0
end
