Member Function Documentation

virtual void HessianCoefficient::Eval ( DenseMatrix K,
ElementTransformation T,
const IntegrationPoint ip 
)
inlinevirtual

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.

virtual void HessianCoefficient::EvalGrad ( DenseMatrix K,
ElementTransformation T,
const IntegrationPoint ip,
int  comp 
)
inlinevirtual

Evaluate the derivative of the matrix coefficient with respect to comp in the element described by T at the point ip, storing the result in K.
