TaoALMMGetMultipliers#

Retrieve a pointer to the Lagrange multipliers.

Synopsis#

#include "petsctao.h" 
PetscErrorCode TaoALMMGetMultipliers(Tao tao, Vec *Y)

Input Parameter#

Output Parameter#

  • Y - vector of Lagrange multipliers

Notes#

For problems with both equality and inequality constraints, the multipliers are combined together as Y = (Ye, Yi). Users can recover copies of the subcomponents using index sets provided by TaoALMMGetDualIS() and use VecGetSubVector().
