Determine if model is static or dynamic
B = isstatic(sys) returns 1 (true) if the model sys is a static model, and and 0 (false) if sys has dynamics such as states or delays. If sys is a model array, then B is true if all models in sys are static.
Model or array to check, specified as an input-output model or model array. Input-output models include dynamic system models such as numeric LTI models and generalized models. Input-output models also include static models such as tunable parameters or generalized matrices.
