Detailed Description

template<class VECTOR>
class MathTL::ROWMethod< VECTOR >

The following class is an abstract base for an s-stage Rosenbrock-Wanner (ROW-) method for the numerical solution of (abstract) nonautonomous initial value problems of the form

u'(t) = F(t, u(t)), u(0) = u_0.

Essentially, a ROW-method is a W-method with T = F_v(t_m,u^{(m)}) and g = F_t(t_m,u^{(m)}, see w_method.h for details.
