Detailed Description

template<typename _Scalar>
class crocoddyl::ResidualModelJointAccelerationTpl< _Scalar >

Define a joint-acceleration residual.

This residual function is defined as \(\mathbf{r}=\mathbf{u}-\mathbf{u}^*\), where \(\mathbf{u},\mathbf{u}^*\in~\mathbb{R}^{nu}\) are the current and reference joint acceleration, respectively. Note that the dimension of the residual vector is obtained from StateAbstract::nv, as it represents the generalized acceleration.

Both residual and residual Jacobians are computed analytically.

As described in ResidualModelAbstractTpl(), the residual value and its Jacobians are calculated by calc and calcDiff, respectively.
