jacobian()#
- QuadraticOperator.jacobian(state, input_=None)[source]#
Construct the state Jacobian of the operator: \(\ddqhat\Ophat_{\ell}(\qhat,\u) = \Hhat[(\I_r\otimes\qhat) + (\qhat\otimes\I_r)]\).
- Parameters:
- state(r,) ndarray or None
State vector.
- input_(m,) ndarray or None
Input vector (not used).
- Returns:
- jac(r, r) ndarray
State Jacobian \(\Hhat[(\I_r\otimes\qhat) + (\qhat\otimes\I_r)]\).
