Simulink Control Design™ - MathWorks

• NumSamples is set such that the frequency response estimation includes the lower
  end of the frequency range.

Other random options have default values.

'OptionName',OptionValue

Signal characteristics, specified as comma-separated option name and option value pairs.

Option Name Option Value

'Amplitude' Signal amplitude.

Default: 1e-5

'Ts' Sample time of the chirp signal in seconds.

Default: 1e-3

'NumSamples' Number of samples in the Random signal.

Default: 1e4

'Stream' Random number stream you create using the MATLAB command

RandStream. The state of the stream you specify stores with the

input signal. This stored state allows the software to return the

same result every time you use generateTimeseries and

frestimate with the input signal.

Default: Default stream of the MATLAB session

Examples

Create a Random input signal with 1000 samples taken at 100 Hz and amplitude of 0.02:

input = frest.Random('Amplitude',0.02,'Ts',1/100,'NumSamples',1000);

Create a Random input signal using multiplicative lagged Fibonacci generator random
stream:

% Specify the random number stream
stream = RandStream('mlfg6331_64','Seed',0);

% Create the input signal
input = frest.Random('Stream',stream);
