equivalent of matlab -r "code_name(arg1,arg2,...)"

[Johann Cohen Tanugi]

hi there,
I have a code which defines a function in order to be able to pass 
arguments on the command line. So in matlab I do :
matlab -r "my_code(arg1, arg2, arg3,...)"
This seems to work well and is the only way I found to easily pass 
arguments (I am a total newbie, if someone knows better, I am all ears).
I tried to run the same script with octave, and I figured that the 
option --eval is what I need in order to replace the -r matlab option.
But when I type octave --eval "my_code(arg1, arg2, arg3,...)" my code 
seems to hang : It is a fairly complex double integral, but on matlab it 
seems to be proceeding normally.

So before I try to debug, I wanted to know if there was anything I 
should worry about with this --eval.
thanks in advance for the help,
Johann
