Hi,
for instance, string variables are '2456.00A', '2501A',...
How can I delete letters in a string variable?
Thanks in advance.

To detect which charectors are letters, you can use the function isletter. Then just simply delete the ones that are letters
Example:
yourString = '2456.00A';
deleteMe = isletter(yourString); % Detect which ones are letters
yourString(deleteMe) = []; % Delete the letters
disp(yourString) % Display the result

s={'2456.00A', '2501A'};
out=cellfun(@(x) x(regexp(x,'[^a-zA-Z]')),s,'un',0)
