TaoComputeJacobianState#

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

Synopsis#

#include "petsctao.h" 
PetscErrorCode TaoComputeJacobianState(Tao tao, Vec X, Mat J, Mat Jpre, Mat Jinv)

Collective

Input Parameters#

tao - the Tao solver context
X - input vector

Output Parameters#

J - Jacobian matrix
Jpre - matrix used to construct the preconditioner, often the same as J
Jinv - unknown

Note#

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