TaoComputeJacobian

Computes the Jacobian matrix that has been set with TaoSetJacobianRoutine().

Synopsis

#include "petsctao.h" 
PetscErrorCode TaoComputeJacobian(Tao tao, Vec X, Mat J, Mat Jpre)
Collective on Tao

Input Parameters

solver - the Tao solver context
xx - input vector

Output Parameters

H - Jacobian matrix
Hpre - Preconditioning matrix

Notes

Most users should not need to explicitly call this routine, as it is used internally within the minimization solvers.

TaoComputeJacobian() is typically used within minimization implementations, so most users would not generally call this routine themselves.
