condition_col = 'codition1'
condition_col = cellstr(condition_col);
data = num2cell(data);
for i = 1:length(data)
    if strcmpi(data(i,5),1) && data(i,6)> 5 && strcmpi(data(i,5), 2) && data(i,6) < 5
        data{i} = [data, condition_col];
    end
end

following code doesn't work, any help

The code makes no sense at all and there's no comment explaining what it's meant to do.

Can you explain with examples using valid matlab syntax what it is you want to do?

I just want to add a new variable to one column in it's each row when a certain conditon is met. For example:

if col5(1,1)==1 && col6 <5
%then add variable1 in the corresponding row to col10
elseif col5(1,1)==2 && col6 >5
%then add variable2 in the corresponding row to col10
end

See if this helps to get you on the right track:

% set up dummy data to work with
data = rand(20,1);
data = array2table(data);
data.Properties.VariableNames = {'MyColumnName'};
for ii = 1 : height(data)
	% example condition, use your condition instead
	if data.MyColumnName(ii) < 0.5
		data.codition1{ii} = 'Condition Met';
	else
		data.codition1{ii} = '';
	end
end
