I WANT TO REMOVE LINES WHICH CONTAINS CHARACTERS AND ALPHABETS AND I WANT TO RETAIN ONLY NUMBERS IN A TEXT DOCUMENT USING MATLAB. SOME ONE PLEASE HEP ME IN DOING SO. In the above text file, there are some lines like 'HUMAN DETECTED' 'Animal Detected'. I want to create a new file which contains only numbers and not these lines containing alphabetic messages.
