范例

基本范例  (2)

一个离散时间系统：

Wolfram Language code: DiscreteTimeModelQ[StateSpaceModel[{{{a}}, {{b}}, {{c}}, {{0}}}, SamplingPeriod -> τ, SystemsModelLabels -> None]]

选择离散时间模型：

Wolfram Language code: Cases[{StateSpaceModel[{{{a}}, {{b}}, {{c}}, {{0}}}, SamplingPeriod -> 1, SystemsModelLabels -> None], a, StateSpaceModel[{{{a}}, {{b}}, {{c}}, {{0}}}, SamplingPeriod -> τ, SystemsModelLabels -> None]}, _ ? DiscreteTimeModelQ]
