Question

I would like to do something similar to the following, except I would only like to remove ‘g’ and’g’ because they are the duplicates that occur one after each other. I would also like to keep the sequence the same.

Any help would be appreciated!!!

I have this cell array in MATLAB:

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


ans =

'd'    'f'    'a'    'w'    'a'    'h'

Answer 1

There was an error in my first answer (below) when used on multiple duplicates (thanks grantnz). Here’s an updated version:

>> y = { 'd' 'f' 'a' 'g' 'g' 'w' 'a' 'h' 'h' 'i' 'i' 'j'};
>> i = find(diff(char(y)) == 0);
>> y([i; i+1]) = []

y = 

    'd'    'f'    'a'    'w'    'a'    'j'

OLD ANSWER

If your “cell vector” always contains only single character elements you can do the following:

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

y = 

    'd'    'f'    'a'    'g'    'g'    'w'    'a'    'h'

>> y(find(diff(char(y)) == 0) + [0 1]) = []

y = 

    'd'    'f'    'a'    'w'    'a'    'h'
