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.
