Final time of simulation for frequency response estimation
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.
input — Input signal
frest.Sinestream object |
frest.Chirp object |
Input signal for frequency response estimation with the
frestimate function, specified as one of the following objects.
You can create input signals at the command line or export signals that you create using the Model Linearizer app.
tfinal — Final simulation time
Final time for a simulation performed during frequency response estimation using the specified input signal, returned as a scalar value.
You can view the simulation time for an input signal when estimating a frequency response using the Model Linearizer app. To do so, in the MATLAB Workspace or Linear Analysis Workspace section, select the input signal. The app shows the simulation time in the Variable Preview section.
