TaoComputeDualVariables

Computes the dual vectors corresponding to the bounds of the variables

Synopsis

#include "petsctao.h" 
PetscErrorCode TaoComputeDualVariables(Tao tao, Vec DL, Vec DU)

Collective

Input Parameter

• tao - the Tao context

Output Parameters

• DL - dual variable vector for the lower bounds

• DU - dual variable vector for the upper bounds

Note

DL and DU should be created before calling this routine. If calling this routine after using an unconstrained solver, DL and DU are set to all zeros.
