Constructor & Destructor Documentation

◆ AlgebraicSpaceHierarchy()

mfem::ceed::AlgebraicSpaceHierarchy::AlgebraicSpaceHierarchy ( FiniteElementSpace & fespace )

Construct hierarchy based on finest FiniteElementSpace.

The given space is a real (geometric) space, but the coarse spaces are constructed semi-algebraically with no mesh information.
