virtual void mfem::MatrixCoefficient::Eval ( DenseMatrix K,
ElementTransformation T,
const IntegrationPoint ip 
pure virtual

Evaluate the matrix coefficient in the element described by T at the point ip, storing the result in K.

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).
