A first trick is to specify in the Octave terminal:

debug_on_error (1)

before trying again. Then Octave will stop (in debug mode) at the offending
statement. At that point (in the middle of a function) you can find out the
state and values of variables by just typing their name. You'll soon find
out which of the variables or function values is still undefined.

FYI, this is one of the great assets of a script language like Octave
offers.

(To quit debug mode, type 

dbquit

)
If the debug_on_error setting gets in the way later on you can repeat it
with a value of 0 instead of 1.
BTW next time mention your operating system and Octave version.
