Re: Help with octave C++ function

I have just been trying to debug this manually.  I will take your advice with gdb.  May I ask which of my indexes you were referring to?

Thank you for your response

Without much digging into your code it smells to me like indexes getting

How are you trying to debug this? I would suggest you to use gdb,
perhaps with a nice front-end such as eclipse.

Good luck.
