Detailed Description
template<int D>
class Pscf::Rpg::LrAmCompressor< D >
class Pscf::Rpg::LrAmCompressor< D >
Linear-response Anderson mixing compressor.
Specializations of this template with D=1, 2, and 3 are derived from specializations of the base class template Rp::LrAmCompressor, and inherit their public interface and almost all of their source code from this base class.
