Re: Can we turn "Warnings" off?

So, no, there is no way to turn off all warning automatically.

You can however eliminate most of them if you start octave with
        octave --traditional
Or if you do "who -a" from within octave, the builtin variables
list is a set of flags for doing things to the octave interpreter,
such as 
        empty_list_elements_ok = 1
or
        implicit_str_to_num_ok = 1
Traditional sets a bunch of these variables to specific values:

        
        PS1                           = ">> "
        PS2                           = ""
        beep_on_error                 = 1
        default_save_format           = "mat-binary"
        define_all_return_values      = 1
        do_fortran_indexing           = 1
        crash_dumps_octave_core       = 0
        empty_list_elements_ok        = 1
        implicit_str_to_num_ok        = 1
        ok_to_lose_imaginary_part     = 1
        page_screen_output            = 0
        prefer_column_vectors         = 0
        print_empty_dimensions        = 0
        treat_neg_dim_as_zero         = 1
        warn_function_name_clash      = 0
        whitespace_in_literal_matrix  = "traditional"
