I need to update my comparison expression , I dont know how to do it. All my comparison expressions are stored in a cells.
stringDAT = 'bat cat can car coat Name CUT ct CAT-scan'
expression = 'Name'
startIndex = regexp(stringDAT,expression)
I want the comparison expression need to be updated.
for i = 1:10
expression = value(i)
startIndex = regexp(StringDAT,expression)
where value has 10 different characters stored in form of cell.

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.
