RaiseAction.h File Reference

Routines for making float-precision Action's act like double-precision ones, accepting some loss of accuracy. Used in the context of backwards refinement or krylov solution that operates in mixed precision. (e.g. use a float- precision preconditioner to solve a double-precision forward operator) More...
