Concept definition

template<typename VectorType>
concept concepts::is_dealii_petsc_matrix_type = 
    internal::is_dealii_petsc_matrix_type<VectorType>

Detailed Description

A concept that tests whether a given template argument is a deal.II matrix type that internally builds on PETSc functionality. This concept is used to constrain some classes that implement advanced functionality based on PETSc and that requires that the matrix it works on are PETSc matrices. This includes, for example, the time stepping and nonlinear solver classes in namespace PETScWrappers.
