SNESLineSearchSetNorms#
Sets the computed norms for the current solution X, the current update Y, and the current function value F.
Synopsis#
#include "petscsnes.h" 
PetscErrorCode SNESLineSearchSetNorms(SNESLineSearch linesearch, PetscReal xnorm, PetscReal fnorm, PetscReal ynorm)
Collective
Input Parameters#
- linesearch - the line search context 
- xnorm - The norm of the current solution 
- fnorm - The norm of the current function, this is the - norm(function(X))where- Xis the current solution
- ynorm - The norm of the current update (after scaling by the linesearch computed lambda) 
Note#
This is called by the line search routines to store the values they have just computed
