Detailed Description

Default parameters common to most Belos solvers.

Both Belos solvers and users may override these defaults. Real floating-point values are deliberately double, in order to avoid issues with constexpr construction of certain MagnitudeTypes.

const double Belos::DefaultSolverParameters::convTol = 1.0e-8

static

Default convergence tolerance.

This assumes that implicit conversion from double to Teuchos::ScalarTraits<Scalar>::magnitudeType always works, but Belos already assumed that. See discussion starting here:

Initialization of values moved to BelosTypes.cpp to fix ODR-used issues
