Output Arguments

tfinal

Final time of simulation performed during frequency response estimation using the input

signal input.

For example, the command sysest = frestimate(mdl,io,input) performs

frequency response estimation on the Simulink model specified by mdl with the

linearization I/O set io. The estimation uses the input signal input. The command

tfinal = getSimulationTime(input) returns the simulation time at the end of the

simulation performed by frestimate.

Examples

Retrieve Simulation Time for Frequency Response Estimation

Create a sinestream input signal.

input = frest.Sinestream('Amplitude',1e-3,...

'Frequency',logspace(1,3,50),...

'SamplesPerPeriod',40,'FreqUnits','Hz');

The sinestream signal input includes 50 frequencies spaced logarithmically between 10

Hz and 1000 Hz. Each frequency is sampled 40 times per period.

Calculate the final simulation time of an estimation using that signal.

tfinal = getSimulationTime(input)

tfinal = 4.4186

tfinal indicates that frequency response estimation of any model with this input signal

would simulate the model for 4.4186 s.
