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 on Tao

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.
