I want to create a new file ('vectors2.m') that is a copy of the first, and search for one vector ('vectorB') and randomly sort the values into two groups (e.g. 'vectorB1' and 'vectorB2'), in the end replacing 'vectorB' with 'vectorB1' and 'vectorB2'.

Files ending in .m are m-files that are functions or scripts meant to be run, not read with textscan etc. What are the *exact* contents of the file vectors.m? Can you post the contents exactly as it appears in the file?
