TransferFunction[ System1]

Aliases: none

Description: $TransferFunction[System1]$ returns the transfer function associated with the state space representation of $System1$.

Arguments: System1

Comments / Limitations: More complete documentation can be found in the Control Systems Professional manual. Changes to the CSP II package, since the CSP I require that inside NCControl.m we set the option

ReductionMethod $\to$ NCInverse

for TransferFunction. For systems with commutative entries one still gets a correct answer from TransferFunction even with this option set. However, it may look different from that produced by CSP. Thus for a commutative $[A, B, C, D]$ system, one may want use the option

ReductionMethod $\to$ DeterminantExpansion

which gives the same answer as the CSP default.
