The command cannot be used for models with a singular E matrix. Use the "isproper" command to first derive an explicit representation of your model

The command cannot be used for continuous-time models with delays. Use the "pade" command to approximate delays

The command cannot be used for improper models (models with more zeros than poles in some I/O pair)

The command cannot be used for models with internal delays.

The command cannot be used for continuous-time models with internal delays. Use the "pade" command to approximate such delays.

The command cannot be used for discrete-time models with internal delays. Use the "absorbDelay" command to replace such delays by poles at z=0
