SNESLineSearchVIProjectFn#

A prototype of a SNES function that computes the norm of the active set variables in a vector in a VI solve, passed to SNESLineSearchSetVIFunctions()

Synopsis#

PETSC_EXTERN_TYPEDEF typedef PetscErrorCode          SNESLineSearchVINormFn(SNES snes, Vec f, Vec u, PetscReal *fnorm);

Calling Sequence#

snes - SNES context
f - the vector to compute the norm of
u - the current solution, entries that are on the VI bounds are ignored
fnorm - the resulting norm

Note#

The deprecated SNESLineSearchVINormFunc still works as a replacement for SNESLineSearchVINormFn *.

Level#

advanced
