Re: octave-mode: Indentation of multi-line expressions?

[Klaus-Dieter Bauer]

For reference, I do not need that  e x a c t  formatting. Any reasonable 
indentation will do. Only, while cleaning up project code, the default behavior 
did not give useful results. For instance in the (anonymized) code sample:

    for i = 1:imax
        % ...
        if not(load_from_file)
            [p_ext,c_ext,time,origin] = calculate_coefficients(
                                                
a,long,list,of,arguments,as,existing,
                                                in,the,code,base,followed,by,
                                                'an expression in a string'
                                            );
        else
            % ...
        end
        % ...
    end

Recommendations on how to write the code in a way that plays more nicely with 
the indentation in Emacs would help as well. For reference, Octave's

    Edit > Format > Indent Code

will produce an unhelpful

    [p_ext,c_ext,time,origin] = calculate_coefficients(
    a,long,list,of,arguments,as,existing,
    in,the,code,base,followed,by,
    'an expression in a string'
    );

and Matlab's "Smart Indent" will produce

    [p_wbt,cond_wbt,time,source] = wbt_surfacewise_ngauss(...
        name,p,e,source,ar,as,at,nu_min,d_nu,nu_max,ngauss_steps,mult,...
        'savesys=0; save_and_collect=0; externalsolver=1; 
mlv_source_loaded=1;'...
        );

but requires explicit continuation syntax ("...").

best regards,
Klaus
