Detailed Description

template<template< class, class > class ConcreteSolver, typename Scalar>
struct Amesos2::solver_supports_scalar< ConcreteSolver, Scalar >

Check whether a solver supports a scalar type.

A meta-function for checking a solver's support for a scalar. The special-case is a Meta::nil_t list, which we are going to interpret as the solver supporting any and all types. If a solver's supported_scalars type-list is nil, this meta-function returns true always. Otherwise, it checks whether the given type is in the solver's supported_scalars list.
