ho to get rid of repeated cells in cells arrays functions

Hello..

I have a cells array as follows:

contextt = 

      {24x1 cell}    {25x1 cell}    {26x1 cell}

I need to find the repeated cells in each column of the cells..

I used the following code , but doesn't help

[~,idx]=unique(cell2mat(contextt),'rows');
context_arr=contextt(idx,:)

with the following error:

Cannot support cell arrays containing cell arrays or objects

I changed the command 'rows' to 'columns' in the secod fucntion , but also doesn't work... also I want to results to be shown for the cells array contextt any advice Regards

 contextt={{1 2 3 4},{1 1 2 5},{2 2 2 6 7}}
 out=cellfun(@(x) unique(cell2mat(x)),contextt,'un',0)

or

out=cellfun(@(x) num2cell(unique(cell2mat(x))),contextt,'un',0)

Hi Azzi.. it gives me error message:

Error using cell2mat (line 46)
All contents of the input cell array must be of the same data type.

Error in @(x)unique(cell2mat(x))

my data is in the type of characters (same like this: GO:0008150)

[Azzi Abdelmalek]

can you post a sample of your data?

[Azzi Abdelmalek]

try this

contextt={{'1' '20' '3'},{'1' '1' '2'},{'2' '2' '2'}}
out=cellfun(@(x) unique(x),contextt,'un',0)

@Azzi: Would this simpler version work also:

out=cellfun(@unique, contextt, 'un', 0)

? I cannot try it currently. Anonymous functions are slower than function handles in CELLFUN.

my data is same like this:

       'a0'    'a0.b0'    'a0.b0.d6'               
       'a0'    'a0.d2'    'a0.d2.c2'               
      'a0'    'a0.d2'    'a0.d2.b1'                
      'a0'    'a0.e0'    'a0.e0.d8'                
      'a0'    'a0.c1'    'a0.c1.d9'                
      'a0'    'a0.c1'    'a0.c1.c3'
