Simulink.sdi.close

Close the Simulation Data Inspector

Syntax

Simulink.sdi.close

Simulink.sdi.close('filename')

Description

Simulink.sdi.close closes the Simulation Data Inspector.

Simulink.sdi.close('filename') closes the Simulation Data Inspector and saves the data in the file, filename.

Examples

Close the Simulation Data Inspector from the Command Line

You can close the Simulation Data Inspector from the MATLAB^® command line when you have finished inspecting and analyzing your data.

Simulink.sdi.close

Create a Run and View the Data

This example shows how to create a run, add data to it, and then view the data in the Simulation Data Inspector.

Create Data for the Run

Create timeseries objects to contain data for a sine signal and a cosine signal. Give each timeseries object a descriptive name.

time = linspace(0,20,100);

sine_vals = sin(2*pi/5*time);
sine_ts = timeseries(sine_vals,time);
sine_ts.Name = 'Sine, T=5';

cos_vals = cos(2*pi/8*time);
cos_ts = timeseries(cos_vals,time);
cos_ts.Name = 'Cosine, T=8';

Create a Run and Add Data

Use the Simulink.sdi.view function to open the Simulation Data Inspector.

Simulink.sdi.view

To import data into the Simulation Data Inspector from the workspace, create a Simulink.sdi.Run object using the Simulink.sdi.Run.create function. Add information about the run to its metadata using the Name and Description properties of the Run object.

sinusoidsRun = Simulink.sdi.Run.create;
sinusoidsRun.Name = 'Sinusoids';
sinusoidsRun.Description = 'Sine and cosine signals with different frequencies';

Use the add function to add the data you created in the workspace to the empty run.

add(sinusoidsRun,'vars',sine_ts,cos_ts);

Plot the Data in the Simulation Data Inspector

Use the getSignalByIndex function to access Simulink.sdi.Signal objects that contain the signal data. You can use the Simulink.sdi.Signal object properties to specify the line style and color for the signal and plot it in the Simulation Data Inspector. Specify the LineColor and LineDashed properties for each signal.

sine_sig = getSignalByIndex(sinusoidsRun,1);
sine_sig.LineColor = [0 0 1];
sine_sig.LineDashed = '-.';

cos_sig = sinusoidsRun.getSignalByIndex(2);
cos_sig.LineColor = [0 1 0];
cos_sig.LineDashed = '--';

Use the Simulink.sdi.setSubPlotLayout function to configure a 2-by-1 subplot layout in the Simulation Data Inspector plotting area. Then use the plotOnSubplot function to plot the sine signal on the top subplot and the cosine signal on the lower subplot.

Simulink.sdi.setSubPlotLayout(2,1);

plotOnSubPlot(sine_sig,1,1,true);
plotOnSubPlot(cos_sig,2,1,true);

Close the Simulation Data Inspector and Save Your Data

When you have finished inspecting the plotted signal data, you can close the Simulation Data Inspector and save the session to an MLDATX file.

Simulink.sdi.close('sinusoids.mldatx')
