| void BiQuad2DFiniteElement::CalcDShape | ( | const IntegrationPoint & | ip, |
| DenseMatrix & | dshape | ||
| ) | const [virtual] |
virtual function which evaluates the values of all partial derivatives of all shape functions at a given point ip and stores them in the matrix dshape (Dof x Dim) (9 x 2) so that each row contains the derivatives of one shape function
