Hi Nadeera,
I am assuming that you have a set of cell arrays each of which represents the data set and you would like to extract the data which does not match some specific string. Please find below a sample script demonstrating this:
%Assume that cell array A represent the data set.
>>B={'SP','NS','GX'};
>>C={};
>>len=length(A);
>>for i=1:len
if( isempty( find(cellfun('length',regexp(B,A{i})) == 1)))
C{end+1}=A{i}
end
end
The above script will extract all the elements in 'A' which are not present in 'B' and store them in another cell array 'C'.
