According to the tickets, it seems that the shift are implemented for real matrices, isn't it ?
There is an alternate interface
http://www.scipy.org/scipy/scipy/browser/trunk/scipy/sparse/linalg/eigen/arp... that should solve the shift-invert problem for real (double) matrices. This functionality needs to be folded into the other (arpack.py) interface and extended to work for all matrix types. You might be able to make it work for you until we get to that.
OK, I'll try this, hoping that it behaves like MAtlab's version ;) I'll keep the list informed !
