OK, I'll try this, hoping that it behaves like MAtlab's version ;)
I'll keep the list informed !

I tried to use it, but I don't get the same result as Matlab or a standard eigen analysis.
I'd like to get the eigenvalues that are strictly greater than zero. Is it possible with one of the speigs option ?

Is it planned to add the sigma keyword to the ARPACK_eigs function ? (that's how my problem is solved by Matlab, that's why I'm asking)
