Function<double,NDIM> madness::NonlinearSolverND< NDIM >::update ( const Function< double, NDIM > &  u, const Function< double, NDIM > &  r, const double  rcondtol = 1e-8, const double  cabsmax = 1000.0  )

inline

Computes next trial solution vector.

You are responsible for performing step restriction or line search (not necessary for linear problems).

Parameters

u	Current solution vector
r	Corresponding residual

Returns

Next trial solution vector

Parameters

[in]	rcondtol	rcond less than this will cause the subspace to be shrunk due to linear dependence
[in]	cabsmax	maximum element of c greater than this will cause the subspace to be shrunk due to linear dependence
