i have also another question for you about this code:
if i run it and then i type at the octave prompt something like:
octave2.1:10>r
error: `r' undefined near line 10 column 1

also if i take a look at:
octave2.1:11>whos

then i cannot see anything regarding the variables i defined inside the script;
but i do not understand why; i can not even retrieve the values
interesting for my calculation...
