Detailed Description

template<typename T_T, typename T_Store = std::vector<T_T>>
struct codi::Hessian< T_T, T_Store >

Default implementation of the Hessian interface.

Running index speed: j (fastest), i, k (slowest).

Data is stored in an array of row-major matrices.

Template Parameters

T_T	Data type in the Hessian.
T_Store	Storage allocator. Should implement the standard vector interface.
