#include <deal.II/base/template_constraints.h>

Concept definition

template<typename MatrixType, typename VectorType>
requires(const MatrixType &A, VectorType &dst, const VectorType &src) {
A.vmult(dst, src);

Detailed Description

A concept that tests whether objects of type MatrixType can act as linear operators on VectorType. In practice, that means that MatrixType must have a vmult() member function that can take a VectorType object as input and produce another VectorType as output (both objects being taken as arguments to the vmult() function).
