Save data from Simulink Scope
显示 更早的评论
I have checked "Log data to workspace" in the Simulink Scope under the Logging pane, but after running the simulation, no data are saved to the workspace.
Is there any additional setting required to ensure that the data are stored correctly?
Thank you

I have this setting: is it correct?
DataScope1 is strored inside out?
How to get data out and plot again the same way as on oroginal scope 'cause when right clickng there is no option to plot ? ... something as plot(ScopeData1)

"I have this setting: is it correct?"
It's correct if you want all of your logged variables to be contained within a single variable called "out". Uncheck the box if you'd rather have all of your logged variables be sent to the workspace individually.
"[ScopeData1] is strored inside [the variable named] out?"
Yes
"How to get data out and plot again the same way as on oroginal scope 'cause when right clickng there is no option to plot ? ... something as plot(ScopeData1)"
For plotting:
plot(out.ScopeData1)
For access more generally, see:
See Simulink.Simulation.Dataset for how to work with datasets. Or, change the Save Format in the Logging properties of the scope to an alternative format if preferred.

This is a very common issue when working with Simulink Scope logging. Looking at your screenshot, your Save format is set to Dataset (ScopeData1).
When saving as Dataset, MATLAB doesn't output plain arrays directly to the Workspace; instead, it wraps the time-series data inside a Simulink.SimulationData.Dataset object.
Extract data from the Dataset object
Check your MATLAB Workspace for the variable named ScopeData1 (or out.ScopeData1 if single simulation output logging is enabled). You can extract the signal values using:
mySignal = ScopeData1.getElement(1).Values;
plot(mySignal.Time, mySignal.Data);
Also, make sure Single simulation output isn't wrapping everything into an out object (e.g., check for out.ScopeData1 in your workspace)!.
