Public Member Functions
	MatrixConstantCoefficient (const DenseMatrix &m)
	Construct using matrix m for the constant. More...

virtual void	Eval (DenseMatrix &M, ElementTransformation &T, const IntegrationPoint &ip)
	Evaluate the matrix coefficient at ip. More...

Public Member Functions inherited from mfem::MatrixCoefficient
	MatrixCoefficient (int dim, bool symm=false)
	Construct a dim x dim matrix coefficient. More...

	MatrixCoefficient (int h, int w, bool symm=false)
	Construct a h x w matrix coefficient. More...

void	SetTime (double t)
	Set the time for time dependent coefficients. More...

double	GetTime ()
	Get the time for time dependent coefficients. More...

int	GetHeight () const
	Get the height of the matrix. More...

int	GetWidth () const
	Get the width of the matrix. More...

int	GetVDim () const
	For backward compatibility get the width of the matrix. More...

bool	IsSymmetric () const

virtual void	EvalSymmetric (Vector &K, ElementTransformation &T, const IntegrationPoint &ip)
	Evaluate the upper triangular entries of the matrix coefficient in the symmetric case, similarly to Eval. Matrix entry (i,j) is stored in K[j - i + os_i] for 0 <= i <= j < width, os_0 = 0, os_{i+1} = os_i + width - i. That is, K = {M(0,0), ..., M(0,w-1), M(1,1), ..., M(1,w-1), ..., M(w-1,w-1) with w = width. More...
