Shock_decomposition and DiffuseKalmanSmoother1

Greetings Dear all,
I have a state space model and I want to make a shock decompositions. I understand that Dynare uses the function: DiffuseKalmanSmoother1, based on the work of Koopman and Durbin (2003): “Filtering and Smoothing of State Vector for Diffuse State Space Models”, I would apply it to my model and I would like to have more details about the inputs of this function.

I’m reading the work of Koopman and Durbin, but still have doubts to implement the inputs of the function: DiffuseKalmanSmoother1.

Thank you very much for your attention
I apologize for my writing, I’m Peruvian.
