Definition at line 972 of file coefficient.hpp.

Constructor & Destructor Documentation

◆ MatrixConstantCoefficient()

mfem::MatrixConstantCoefficient::MatrixConstantCoefficient ( const DenseMatrix & m )

inline

Construct using matrix m for the constant.

Member Function Documentation

◆ Eval() [1/2]

virtual void mfem::MatrixCoefficient::Eval

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).

◆ Eval() [2/2]

virtual void mfem::MatrixConstantCoefficient::Eval	(	DenseMatrix &	M,
		ElementTransformation &	T,
		const IntegrationPoint &	ip
	)

inlinevirtual

Evaluate the matrix coefficient at ip.

Implements mfem::MatrixCoefficient.

Definition at line 982 of file coefficient.hpp.

◆ GetMatrix()

const DenseMatrix& mfem::MatrixConstantCoefficient::GetMatrix ( )

inline

Return a reference to the constant matrix.

Definition at line 985 of file coefficient.hpp.
