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 - Taocontext
- 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.
