Detailed Description
template<typename Scalar>
singleton Hermes::Hermes2D::MeshFunction< Scalar >
Represents a function defined on a mesh.
MeshFunction is a base class for all classes representing an arbitrary function superimposed on a mesh (ie., domain). These include the Solution, ExactSolution and Filter classes, which define the concrete behavior and the way the function is (pre)calculated. Any such function can later be visualized.
(This is an abstract class and cannot be instantiated.)
