SNESLineSearchVINormFn

A prototype of a SNES function that computes the norm of the active set variables in a vector in a variational inequality (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 variational inequality (VI) bounds are ignored

• fnorm - the resulting norm
