Commands for Generating and Simulating Data
You can ge n era te input data and simulate output data using a specified
model structure.
Simulating output data requires that you have a parametric model. For more
information about commands for constructing models, see “Commands for
Constructing Model Structures” on page 2-13.
To generate input data, use
idinput to construct a signal with the desired
characteristics, such as a random Gaussian or binary signal or a sinusoid.
idinput returns a matrix of input values.
Thefollowingtableliststhecommands you can use to simulate output data.
For more information about these commands, see the corresponding reference
pages.

To construct input data
data,usethe
following command:
data = iddata([ ],[u v])
u
is the input data, and v is white noise.
