Detailed Description

Invert Kohn-Sham equations to get effective potential for a given electron density.

Member Function Documentation

diagMatrix InvertKS::precondition ( const diagMatrix grad)
virtual

Override to enable preconditioning: return the preconditioned gradient, given the gradient The last call to compute() is guaranteed to be at the same position, so a cached result may be returned

Reimplemented from Minimizable< diagMatrix >.
