Dear ALPS developers, is it possible to have the coeffcients and eigenvectors of the T-matrix returned from lanczos object in lanczos.h ? I need them (the first component to be exact) for computing the spectral function. I do see the member function t_eigenvectors() in the header, but I wouldn't know exactly how to write the code to get the values since I'm not much into C++. Could you please add a couple of lines of code later to one of the lanczos examples, so it can be helpful for all users ? Best regards, Jessica Alfonsi
