Try strcmp() or strcmpi() to compare a variable to a string constant. Or, if you're comparing against a list of words, use ismember().
if strcmpi(yourAnimal, 'sparrow')
message = sprintf('Your animal is a bird.');
uiwait(helpdlg(message));
end

Your_list={'cat' 'dog' 'horse' 'sparrow' 'swallow' 'dove'}
You can associate to each element a number that indicate if it's an animal or a bird
type=[1 1 1 2 2 2]
message={ 'it''s an animal' 'it''s a bird' }
For example, if
a='cat'
Try to find the answer, you can use ismember function
