Detailed Description

template<typename T, int NDIM>
class madness::Subspace< T, NDIM >

The SubspaceK class is a container class holding previous orbitals and residuals.

The Solver class uses the Krylov Accelerated Inexact Newton Solver (KAIN) accelerate the convergence a given calculation. The KAIN solver needs to store a subspace of previous orbitals and residuals.
