Determine if model has finite coefficients
Create model and check whether its coefficients are all finite.
sys = rss(3); B = isfinite(sys)
B = 1
Create a 1-by-5 array of models and check each model for finite coefficients.
sys = rss(2,2,2,1,5); B = isfinite(sys,'elem')
B = 1 1 1 1 1
When you use the 'elem' input, isfinite checks each model individually and returns a logical array indicating which models have all finite coefficients.
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.
