## Detailed Description

Matrix coefficient defined as a product of a scalar and a matrix.

Definition at line 893 of file coefficient.hpp.

## Constructor & Destructor Documentation

## Member Function Documentation

 void mfem::ScalarMatrixProductCoefficient::Eval ( DenseMatrix & K, ElementTransformation & T, const IntegrationPoint & ip )
virtual

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

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::MatrixCoefficient.
