MATLAB: Ho to get rid of repeated cells in cells arrays functions

Question

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

Answer 1

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