Detailed Description

template<typename T>
class NLTSScheme< T >

Base class for non-linear time stepping schemes.

This is a base class for time stepping schemes for problems that are represented by classes derived from NLTimeAssemble<T>. Cf. the descriptions of NLTimeAssemble<T> for details.

Note:

The template depends on a type T. This type should satisfy the conditions listed in small_matrix.hpp for small matrices.
