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.
