This struct stores the shape functions, their gradients and Hessians evaluated for a one-dimensional section of a tensor product finite element and tensor product quadrature formula in reference coordinates. This data structure also includes the evaluation of quantities at the cell boundary and on the sub-interval \((0, 0.5)\) and \((0.5, 1)\) for face integrals.

| AlignedVector<Number> internal::MatrixFreeFunctions::UnivariateShapeData< Number >::shape_hessians_collocation_eo |

| AlignedVector<Number> internal::MatrixFreeFunctions::UnivariateShapeData< Number >::inverse_shape_values |
Stores the inverse transformation from the data at quadrature points to the basis defined by the shape_values fields. The data at quadrature points is interpreted either implicitly by its polynomial interpolation, or explicitly in terms of separate polynomials such as with the _collocation fields. The size of the array equals the layout of the shape_values array, and it is combined with the shape values array such that this matrix is the pseudo inverse of shape_values. In case the number of 1D quadrature points equals the size of the basis, this array is exactly the inverse of the shape_values array. The length of this array is n_dofs_1d * n_q_points_1d and quadrature points are the index running fastest.
