Definition at line 1951 of file coefficient.hpp.
mfem::MatrixVectorProductCoefficient::MatrixVectorProductCoefficient  (  MatrixCoefficient &  A, 
VectorCoefficient &  B  
) 
Constructor with two coefficients. Result is A*B.
Definition at line 1179 of file coefficient.cpp.

virtual 
Evaluate the vector coefficient at ip.
Implements mfem::VectorCoefficient.
Definition at line 1196 of file coefficient.cpp.
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.
