## Member Function Documentation

 void mfem::VectorRestrictedCoefficient::Eval ( Vector & V, ElementTransformation & T, const IntegrationPoint & ip )
virtual

Evaluate the vector coefficient in the element described by T at the point ip, storing the result in V.

Note
When this method is called, the caller must make sure that the IntegrationPoint associated with T is the same as ip. This can be achieved by calling T.SetIntPoint(&ip).

Implements mfem::VectorCoefficient.

Definition at line 258 of file coefficient.cpp.

 void mfem::VectorRestrictedCoefficient::Eval ( DenseMatrix & M, ElementTransformation & T, const IntegrationRule & ir )
virtual

Evaluate the vector coefficient in the element described by T at all points of ir, storing the result in M.

The dimensions of M are GetVDim() by ir.GetNPoints() and they must be set by the implementation of this method.

The general implementation provided by the base class (using the Eval method for one IntegrationPoint at a time) can be overloaded for more efficient implementation.

Note
The IntegrationPoint associated with T is not used, and this method will generally modify this IntegrationPoint associated with T.

Reimplemented from mfem::VectorCoefficient.
