When you asked this question under the subject "code question", Bret 
Green suggested that you read a basic tutorial on programming.  Please 
do that, then, maybe we can help you.  With your not understanding basic 
programming, we can not help.

The code you posted is not correct octave code, and should not run.  You 
started a function definition but, never ended it.
