TaoComputeResidualJacobian#

Computes the least-squares residual Jacobian matrix that has been set with TaoSetJacobianResidual().

Synopsis#

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

Collective

Input Parameters#

tao - the Tao solver context
X - input vector

Output Parameters#

J - Jacobian matrix
Jpre - Preconditioning matrix

Notes#

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

TaoComputeResidualJacobian() is typically used within least-squares implementations, so most users would not generally call this routine themselves.
