Hi,

Please keep the help mailing list in CC when asking questions about Octave,
so others may benefit from the answer.

In Octave 3.8.2 the command "help autoload" returns the following:

'autoload' is a built-in function from the file 
libinterp/parse-tree/oct-parse.cc

 -- Built-in Function: AUTOLOAD_MAP = autoload ()
 -- Built-in Function: autoload (FUNCTION, FILE)
 -- Built-in Function: autoload (..., "remove")
     Define FUNCTION to autoload from FILE.

     The second argument, FILE, should be an absolute file name or a
     file name in the same directory as the function or script from
     which the autoload command was run.  FILE _should not_ depend on
     the Octave load path.

     ...
     
     If a third argument "remove" is given, the function is cleared and
     not loaded anymore during the current Octave session.

so you are getting that error message because 

1) you are missing the first argument in the call
2) second input argument is supposed to be the absolute path of a file 

so, to make your call work you should use the syntax described in the 
documentation:

autoload ("function_name", canonicalize_file_name ("vadd.oct"), "remove")

where "function_name" should by replaced by the name of the function you want 
to remove 
from the interpreter.

I think the help for the function autoload was clear enough about this,
but if you think it wasn't and you think it may be improved, please propose
any changes you think could make it more easy to follow.

HTH,
c.
