Hi,

I'm new to octave too.
You may use the help from octave or info from a shell.
e.g.

info octave  in a shell
help -i something  in octave

If you run octave --traditional or --braindead then octave will try to
emulate matlab environment but not everything. The builtin variables
what you put in the debut.m will have the values what you given.

I guess you have problem using some functions which are working in
matlab and not all of them working in octave.
I had similar error messages when I tried some matlab functions from
octave. e.g. functions with variable arguments.

Gabor

PS.
I can send you you the converting procedures if you're interested.
  matlab                      -> octave 
function(varargin)               function(...)
varargout=function(something)    [...]=function(something)

	Hello,

	I need to use Octave for educational purposes for students of
	University of Nice, I have rather short time for preparation of tasks
	for them, but I have a lot of problem running Octave probably because
	lack of my experience in this area.

	I have some program files of MatLab that works well in this
	environment and I would like to transfer them to Octave. I read the
	chapter of FAQ "Porting programs from MATLAB to Octave", then I run
	octave from console by command like "octave --traditional". Octave runs
	without error messages, than I put lines

	PS1 = ">> "
	PS2 = ""
	beep_on_error = 1.0
	default_eval_print_flag = 0.0
	default_save_format = "mat-binary"
	define_all_return_values = 1.0
	do_fortran_indexing = 1.0
	empty_list_elements_ok = 1.0
	fixed_point_format = 1.0
	implicit_num_to_str_ok = 1.0
	implicit_str_to_num_ok = 1.0
	ok_to_lose_imaginary_part = 1.0
	page_screen_output = 0.0
	prefer_column_vectors = 0.0
	prefer_zero_one_indexing = 1.0
	print_empty_dimensions = 0.0
	treat_neg_dim_as_zero = 1.0
	warn_function_name_clash = 0.0
	whitespace_in_literal_matrix = "traditional"

	in file that I call debut.m and run command "source (debut.m)"

	as result I have next error messages:

	error: can't perform structure reference operations for <unknown type> type
	error: evaluating expression
	error: evaluating argument list element number 1
	error: evaluating index expression near line 1, column 1

	Could you tell me, what is wrong, what are the correct actions that
	should be done for resolving this problem? By the way, I did not found
	in my any working directories file .octaverc, in which you proposed put,
	if I understand right, command lines above. Should I create it? With
	what content?

	I am highly appreciate your prompt help

	Sincerely yours Valeriy Sterligov
