State residual.
This residual function defines the state tracking as \(\mathbf{r}=\mathbf{x}\ominus\mathbf{x}^*\), where \(\mathbf{x},\mathbf{x}^*\in~\mathcal{X}\) are the current and reference states, respectively, which belong to the state manifold \(\mathcal{X}\). Note that the dimension of the residual vector is obtained from StateAbstract::get_ndx()
. Furthermore, the Jacobians of the residual function are computed analytically.
As described in ResidualModelAbstractTpl()
, the residual value and its derivatives are calculated by calc
and calcDiff
, respectively.
