Simulink Block for LTI Systems

transfer functions or zero-pole-gain models, as it depends on thechoice of state
coordinates used by the realization algorithm. As a result, you cannot enter
nonzero initial states when you supply TF or ZPK models to LTI blocks in a
Simulink diagram.
Note:
•For MIMO systems, the input delays stored in the LTI object must be either
all positive or all zero.
•LTI blocks in a Simulink diagram cannot be used for FRD models or LTI
arrays.
