template<class PolynomialType, int dim = PolynomialType::dimension, int spacedim = dim>

Table<2, double> FE_Poly< PolynomialType, dim, spacedim >::InternalData::shape_values

Array with shape function values in quadrature points. There is one row for each shape function, containing values for each quadrature point.

In this array, we store the values of the shape function in the quadrature points on the unit cell. Since these values do not change under transformation to the real cell, we only need to copy them over when visiting a concrete cell.

template<class PolynomialType, int dim = PolynomialType::dimension, int spacedim = dim>

Table<2, Tensor<1, dim> > FE_Poly< PolynomialType, dim, spacedim >::InternalData::shape_gradients

Array with shape function gradients in quadrature points. There is one row for each shape function, containing values for each quadrature point.

We store the gradients in the quadrature points on the unit cell. We then only have to apply the transformation (which is a matrix-vector multiplication) when visiting an actual cell.

template<class PolynomialType, int dim = PolynomialType::dimension, int spacedim = dim>

Table<2, Tensor<2, dim> > FE_Poly< PolynomialType, dim, spacedim >::InternalData::shape_hessians

Array with shape function hessians in quadrature points. There is one row for each shape function, containing values for each quadrature point.

We store the hessians in the quadrature points on the unit cell. We then only have to apply the transformation when visiting an actual cell.

template<class PolynomialType, int dim = PolynomialType::dimension, int spacedim = dim>

Table<2, Tensor<3, dim> > FE_Poly< PolynomialType, dim, spacedim >::InternalData::shape_3rd_derivatives

Array with shape function third derivatives in quadrature points. There is one row for each shape function, containing values for each quadrature point.

We store the third derivatives in the quadrature points on the unit cell. We then only have to apply the transformation when visiting an actual cell.
