finding specific elements in a cell vector

Dear all,

I have 10 excel files

some files contains a column

A={

'1W'
  '1W'
  '1W'
  '1W'
  '1W'
  '1W'
  '1W'
  '1W'
  '1W'
  '1W'
  '1W'
}

and some other excel files contain the following column

 A={'1W'
    '1W'
    '1W'
    '1W'
    '1W'
    '2W'
    '1W'
    '1W'
    '2W'
    '1W'
    '1W'}

I want to constract an if statement that will say

 If A contains ONLY '1W'

 'do that'
end

and another one that will say

 if A contains ONLY '1W' AND '2W'

 'do that'
end

thanks

uniqueA = unique(A);
if isequal(uniqueA,{'1W'})
  ...
elseif isequal(uniqueA,{'1W';'2W'})
  ...
end

Answer 2

 n=length(A)
 if sum(cell2mat(regexp(A,'1W')))==n
   test=1
 elseif sum(cell2mat(regexp(A,'1W|2W')))==n
   test=2
 end

[Andrei Bobrov]

>>A={'1W'
    '1W'
    '1W'};
>>n=numel(A);
>> sum(cell2mat(regexp(A,'1W|2W')))==n && sum(cell2mat(regexp(A,'1W')))==n
ans =
     1

?

the order is important, when the first condition is true, the second is skiped even it is true. example:

 if 2==2;test=1;elseif 3==3 test=2,end
%the result will be test=1 ,
