In Matlab I have created a single-output multiple-input fitted model as an idpoly object. This is by using the system identification toolbox and the model is a Box-Jenkins or Transfer Function model. I now want to see what the model does if I put in different inputs (same amount) and no output (model should estimate the output given the input). Yet I did not find a method in Matlab that can do so.
Is there any way I can use an idpoly object (model) in Matlab and use only input to obtain an output? I have tried the command "sim" but it does not do the job.
