class
NonlinearProblem
¶ This is a base class for nonlinear problems which can return the nonlinear function F(u) and its Jacobian J = dF(u)/du.

NonlinearProblem
()¶ Constructor
-
void
form
(GenericMatrix &A, GenericVector &b, const GenericVector &x)¶ Function called by Newton solver before requesting F or J. This can be used to compute F and J together
-
void
F
(GenericVector &b, const GenericVector &x) = 0¶ Compute F at current point x
-
void
J
(GenericMatrix &A, const GenericVector &x) = 0¶ Compute J = F’ at current point x
