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.
