Comment(by barbey):

 My pleasure.

 I changed .dense in .todense() (see github lo branch). Note that the
 LinearOperator version is much longer than the sparse matrix one. Since if
 one only have an analytical formulation, one needs .shape[1] matvec
 operations.

 For the special-purpose LinearOperators, maybe we could add them in a
 separate file. Or what would you think if I write a scikit with them ?
