DiscreteOperators_build_gradient
()¶ Build the discrete gradient operator A that takes a \(w \in H^1\) (P1, nodal
Lagrange
) to \(v \in H(curl)\) (lowest order Nedelec), i.e. v = Aw. V0 is the H(curl) space, and V1 is the P1Lagrange
space.Parameters: - FunctionSpace & V0 (const) – (
FunctionSpace
&) H(curl) space [direction=in] - FunctionSpace & V1 (const) – (
FunctionSpace
&) P1Lagrange
space [direction=in]
Return type: std::shared_ptr< GenericMatrix >
Returns: GenericMatrix
