Detailed Description

Chebyshev polynomial of fermion operator.

This class implements Chebyshev polynomial of a given fermion operator by making use of Clenshow's reccurence formula. The present version is just a rough implementation which assumes to be used accelerate eigenvalue solver. 24 Dec 2011 H.Matsufuru YAML is implemented. [14 Nov 2012 Y.Namekawa] unique_ptr is introduced to avoid memory leaks [21 Mar 2015 Y.Namekawa]
