 I have contacted the author concerning an interface for scipy.


 {{{
 Nils,

 We do not use SciPy and none of my students knows Python,
 so we do not have plans to port BLOPEX to SciPy. However, the abstract
 nature of the BLOPEX code should make such a port reasonably simple
 for anyone, who knows SciPy and Python well.
 E.g., if you want to write an SciPy-BLOPEX interface,
 we can help and advise you if you get any questions about BLOPEX.
 But we do not have the resources to actually do the porting.
 The following paper
 http://math.cudenver.edu/~aknyazev/research/papers/DD16/knyazev_contrib_revised/dd16.pdf
 briefly describes the abstract nature of the BLOPEX code.

 A valid alternative is to write a pure Python code of the BLOPEX
 eigensolver LOBPCG, using, e.g., the MATLAB LOBPCG code
 http://www.mathworks.com/matlabcentral/fileexchange/loadFile.do?objectId=48&objectType=file
 as a starting point. Several people have done a similar thing writing
 Fortran 90 codes of LOBPCG, e.g., in ABINIT. It is not hard.
 If you want to do this, again, we can help and advise you.

 Thanks, Andrew
