OutputDelay
Output delays specified with
• Nonnegative real numbers for continuous-time models (seconds)
• Integers for discrete-time models (number of sample periods)
• Scalar when
or system has uniform output delay
• Vector of length to specify independent delay times for each output
channel
• Array of size -by- -by- -by-. . .-by- to specify d ifferent output
delays for each model in an LTI array.
Notes
String, array of strings, or cell array of st rings
UserData
Arbitrary MATLAB variable
InputName
• String for single-input systems, for example, 'thrust'
• Cellvector ofstringsformulti-inputsystems (withas manycellsasinputs),
for example,
{'u';'w'} for a two-input system
• Padded a rray of strings with as many rows as inputs, for example,
['rudder ' ; 'aileron']
OutputName
Same as InputName (with “input” replaced b y “output”)
InputGroup
Cell arra y. See “Input Groups and Output Groups” on pa ge 2-37.
OutputGroup
