What is comparison expression? You have to give an example, your question is not clear.

sir , in we use string stored in 'expression' to compare with the data in 'stringDAT' , my question is, How we will update the string in 'expression' as the loop updates. As I have many values to compare.

stringDAT = 'bat cat can car coat Name CUT ct CAT-scan'
%   expression = 'Name' ;
% startIndex = regexp(stringDAT,expression) ;

value = {'apple' 'bat' 'cat' 'dog' 'car' 'cut' 'CUT'} ;
startIndex = NaN(size(value)) ;
for i = 1:length(value)
    expression = value{i} ;
    idx = regexp(stringDAT,expression) ;
    if ~isempty(idx)
        startIndex(i) = idx ;
    end
end

Note that NaN means there is no matching.
