thank you for your answer

i'll tend to believe you and i understand what you meant (and thank you for
that) that different inverse() functions may give different results and it's
logical, but what i don't understand is that Octave's inverse function makes
the DSP works and if Octave uses Lapack, using the same funtions on the same
numbers should give the same results, no ? Even if the numbers aren't equal
due to approximation and numbers very close, etc it should give the exact
same results with the same functions. Maybe i didn't tried yet the good
functions ?
