AnalyticFunctionAdapters.h file

Lightweight FunctionBase adapters for analytic vector- and matrix-valued functions defined by a single callable.

Rodin::Variational::RealFunction(F) already wraps a scalar callable with signature (const Geometry::Point&) -> Real. The stock VectorFunction and MatrixFunction only accept either a constant value or a component-wise variadic list of scalar callables. For analytic level sets the natural shape is a SINGLE callable returning the whole vector or matrix; this header adds the missing adapters.

Usage:

Adaptation::AnalyticVectorFunction grad( [&](const Geometry::Point& p) -> Math::SpatialVector<Real> { const auto& c = p.getPhysicalCoordinates(); return analyticLevelSet.grad(c); });

Adaptation::AnalyticMatrixFunction hess( [&](const Geometry::Point& p) -> Math::SpatialMatrix<Real> { const auto& c = p.getPhysicalCoordinates(); return analyticLevelSet.hess(c); });
