overridevirtual

Compute the value and the derivatives of the polynomials at unit_point.

The size of the vectors must either be zero or equal n(). In the first case, the function will not compute these values.

If you need values or derivatives of all polynomials then use this function, rather than using any of the compute_value, compute_grad or compute_grad_grad functions, see below, in a loop over all tensor product polynomials.

Note: Currently, only the vectors values and grads are filled.

◆ clone()

template<int dim>

std::unique_ptr< ScalarPolynomialsBase< dim > > ScalarLagrangePolynomialPyramid< dim >::clone ( ) const

overridevirtual

A sort of virtual copy constructor, this function returns a copy of the polynomial space object. Derived classes need to override the function here in this base class and return an object of the same type as the derived class.

Some places in the library, for example the constructors of FE_Poly, need to make copies of polynomial spaces without knowing their exact type. They do so through this function.

Return the highest polynomial degree of polynomials represented by this class. A derived class may override this if its value is different from my_degree.
