virtual void mfem::VectorCoefficient::Eval 
Evaluate the vector coefficient in the element described by T at the point ip, storing the result in V.
void mfem::VectorCoefficient::Eval 
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.

virtual 
Fill the QuadratureFunction qf by evaluating the coefficient at the quadrature points.
The vdim of the VectorCoefficient should be equal to the vdim of the QuadratureFunction.
Reimplemented from mfem::VectorCoefficient.

void mfem::VectorQuadratureFunctionCoefficient::SetComponent  (  int  index_, 
int  length_  
) 
Set the starting index within the QuadFunc that'll be used to project outwards as well as the corresponding length. The projected length should have the bounds of 1 <= length <= (length QuadFunc  index).
