TaoComputeObjectiveAndGradient#

Computes the objective function value at a given point

Synopsis#

#include "petsctao.h" 
PetscErrorCode TaoComputeObjectiveAndGradient(Tao tao, Vec X, PetscReal *f, Vec G)

Collective

Input Parameters#

  • tao - the Tao context

  • X - input vector

Output Parameters#

  • f - Objective value at X

  • G - Gradient vector at X

Note#

TaoComputeObjectiveAndGradient() is typically used within the implementation of the optimization algorithm, so most users would not generally call this routine themselves.
