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

out=cellfun(@(x) x(regexp(x,'[^a-zA-Z]')),s,'un',0)
