line() is a built in function, and you should not use it for a variable name. What is line 1 of q.m? Are you defining line as something (and thus destroying the built in line function)?

If i change variale line to someone then again it does not work.. and I again reinstall the matlab it again displays same message

Please attach your file q.m.
