TaoTermComputeObjectiveAndGradient#
Evaluate both the value and gradient of a TaoTerm for a given set of solution vector and parameter vector
Synopsis#
#include "petsctao.h"
PetscErrorCode TaoTermComputeObjectiveAndGradient(TaoTerm term, Vec x, Vec params, PetscReal *value, Vec g)
Collective
Input Parameters#
term - a
TaoTermrepresenting a parametric function \(f(x; p)\)x - the solution variable \(x\) in \(f(x; p)\)
params - the parameters \(p\) in \(f(x; p)\) (may be NULL if the term is not parametric)
Output Parameters#
value - the value of \(f(x; p)\)
g - the value of \(\nabla_x f(x; p)\)
