erasing the second duplicate date

Dear all,

I have

A={

 '12/08'
    '01/09'
    '02/09'
    '03/09'
    '03/09'
    '04/09'
    '05/09'
    '06/09'
    '07/09'
    '08/09'
    '09/09'
    '10/09'
    '11/09'
    '12/09'
    '01/10'
    '01/10'
    '02/10'
    '03/10'
    '04/10'
    '05/10'
    '06/10'
    '07/10'
    '08/10'
    '09/10'
    '10/10'
    '11/10'
    '12/10'
    '01/11'
    '01/11'
    '02/11'
    '03/11'
    '04/11'
    '05/11'
    '06/11'
    '07/11'
    '08/11'
    '09/11'
    '10/11'
    '11/11'}

I want to erase from the succesive identical months the second one.

For instance I have

 '01/10'
    '01/10'

I want to erase the second duplicate without using a loop if possible because my vector is huge so at to have

A= {

 '12/08'
    '01/09'
    '02/09'
    '03/09'
    '03/09'
    '04/09'
    '05/09'
    '06/09'
    '07/09'
    '08/09'
    '09/09'
    '10/09'
    '11/09'
    '12/09'
    '01/10'
    '02/10'
    '03/10'
    '04/10'
    '05/10'
    '06/10'
    '07/10'
    '08/10'
    '09/10'
    '10/10'
    '11/10'
    '12/10'
    '01/11'
    '02/11'
    '03/11'
    '04/11'
    '05/11'
    '06/11'
    '07/11'
    '08/11'
    '09/11'
    '10/11'
    '11/11'}

I want to erase from the succesive identical months the second one.

thanks

 unique(a)    % this will sort the result

% if you want to have the same order use this:

 unique(a,'stable')
