I created a matfile as below..
tval=[1 2 3 4 5 6 7]
save filename tval;

now i want to check whether that value contains in the matfile... if it is there i want to display a message 'yes' and if not there display 'no'...
please can someone show me how to check whether the variable's values is in the matfile or not...
