How can I remove duplicates in an array but keep the same order?

Question

I have this cell array in MATLAB:

y = { \'d\' \'f\' \'a\' \'g\' \'g\' \'a\' \'w\' \'h\'}

I use unique(y) to get rid of the dup

Answer 1

In MATLAB R2012a, a new order flag was added:

>> y = {'d' 'f' 'a' 'g' 'g' 'a' 'w' 'h'};
>> unique(y, 'stable')
ans = 
    'd'    'f'    'a'    'g'    'w'    'h'
