  1. Format your code.
  2. Give a description of what it does and what is wrong
  3. State clearly what you need it to do.

But why won't you tell us what the error is???? When I copied and pasted your code into a blank m-file, line 47 was a blank line so I can't even guess what the error is, and I can't even run it because you forgot to list what toolbox was required - the one that has function qfuncinv - so I wasted my time even trying to find out what the error was. Why do you make it hard on us to help you?
