Comment:

 What is the status for the inclusion of this patch ?

 I wrote a package around this whole idea of linear_operators :

 https://github.com/nbarbey/linear_operators

 Among other things I wrote a LinearOperator subclass for band matrices a
 la LAPACK.
 I have also a wrapper for scipy.optimize. For instance, you can perform a
 quadratic minimization on criterion defined using a LinearOperator to
 perform pseudo-inverse estimation.

 Any feedback would be very welcome.
 Test coverage is still quite low and there is still some rough edges.

 Regads,

 Nicolas Barbey
