4 Arrays of LTI Models

4-18

where

• Both zeros and poles are multidimensional cell arrays whose cell entries

contain the v ectors of zeros and poles for each I/O pair of each model in the

LTI array.

•

gains is a multidimensional array containing the scalar gains for each I/O

pair of each model in the array.

• The dimensions (and their lengths) of

zeros, poles,andgains, determine

those o f the LTI array,

sys.

Specifying Arrays of SS Models Using ss

To specify arrays of SS models, use

sys = ss(a,b,c,d)

where a, b, c,anddare real-valued multidimensional arrays of appropriate

dimensions. All models in the resulting array of SS models have the same

number of states, outputs, and inputs.

Note: You cannot use the ss constructor to bui ld an array of state-space

models with different numbers of states. Use stack to build such LTI arrays.

The Size of LTI Array Data for SS Models

The size of the model data for arrays of state-space models is summarized in

the following table.
