Please use subject lines in your emails. Sorting through your multiple subject-less help requests I'd more difficult than it should be. Please makes things easier on the people trying to help you.

When something doesn't work, copy&paste the exact command used and exact error received. Otherwise you're asking us to waste our time guessing. As someone else mentioned, you can use the diary command:
>> help diary

For this one, you posted the text of a getdata function, but the file you posted has a different name, and it appears to contain getdata. How will octave find the function?

The top level function in an m file should have the same name as the file. Any other functions in that file can only be called as subfunctions of that main function.

And the syntax must be correct. Fix the naming issue and use the manual to figure out where your syntax errors are when octave points them out.
