# PETSCDUALSPACELAGRANGE

“lagrange” - A `PetscDualSpaceType` that encapsulates a dual space of pointwise evaluation functionals

## Developer Note

This `PetscDualSpace` seems to manage directly trimmed and untrimmed polynomials as well as tensor and non-tensor polynomials while for `PetscSpace` there seems to be different `PetscSpaceType` for them.
