Detailed Description

template<int dim, typename NumberType, typename ExtractorType_Row, typename ExtractorType_Col>
struct Differentiation::AD::internal::ScalarFieldHessian< dim, NumberType, ExtractorType_Row, ExtractorType_Col >

A helper struct that defines the final return type of Hessian (second derivative) calculations of scalar fields with respect to fields defined by the two extractor-type template parameters. The first, ExtractorType_Row, defines the field that the first derivatives are taken with respect to while the second, ExtractorType_Col, defines the field that the second derivatives are taken with respect to.

using Differentiation::AD::internal::ScalarFieldHessian< dim, NumberType, ExtractorType_Row, ExtractorType_Col >::type
Initial value:
typename HessianType< ExtractorType_Row, ExtractorType_Col >:: template type< rank, dim, NumberType > type

The type associated with computing the Hessian of a scalar field with first respect to the field defined by the ExtractorType_Row and then with respect to the field defined by the ExtractorType_Col.
