hi, i i wana to control simulink and using update with set_param with low-pass filter

i have this error:

A change in parameters 'Numerator' and 'Denominator' for the transfer function block 'Maquette4FreinModifii/FILTRE_passe_haut' causes a structural change in the time domain realization of the transfer function. This is not allowed when the simulation is running.

Caused by: A change in the order of the denominator results in a change in the number of states in the time domain realization of the transfer function.

this command line work only for Gain variable from workspace and not variable low-pass filter from workspace. set_param('Maquette4FreinModifii','SimulationCommand','update')
